Substrates: HIF (hypoxia-inducible factor) is a transcription factor that plays a pivotal role in cellular adaptation to changes in oxygen availability. In the presence of oxygen, HIF is targeted for destruction by an E3 ubiquitin ligase containing the von Hippel-Lindau tumor suppressor protein (pVHL). Human pVHL binds to a short HIF-derived peptide when a conserved proline residue at the core of this peptide is hydroxylated. This protein modifiation may play a key role in mammalian oxygen sensing

Substrates: hypoxia-inducible factor (HIF) is a transcriptional complex that plays a central role in the regulation of gene expression by oxygen. In oxygenated and iron replete cells, HIF-alpha subunits are rapidly destroyed by a mechanism that involves ubiquitylation by the von Hippel-Lindau tumor suppressor (pVHL) E3 ligase complex. This process is suppressed by hypoxia and iron chelation, allowing transcriptional activation. The interaction between human pVHL and a specific domain of the HIF-1alpha subunit is regulated through hydroxylation of a proline residue (HIF-1alpha P564) by HIF-alpha prolyl-hydroxylase (HIF-PH). HIF-PH functions directly as a cellular oxygen sensor

hypoxia-inducible factor-L-proline + 2-oxoglutarate + O2
hypoxia-inducible factor-(4R)-4-hydroxy-L-proline + succinate + CO2
Substrates: mammalian cells respond to changes in oxygen availability through a conserved pathway that is regulated by the hypoxia-inducible factor (HIF). The alpha subunit of the hypoxia-inducible factor is targeted for degradation under normoxic conditions by a ubiquitin-ligase complex that recognizes a hydroxylated proline residue in hypoxia-inducible factor. HIF prolyl hydroxylase is responsible for this posttranslational modification

Substrates: HIF (hypoxia-inducible factor) is a transcription factor that plays a pivotal role in cellular adaptation to changes in oxygen availability. In the presence of oxygen, HIF is targeted for destruction by an E3 ubiquitin ligase containing the von Hippel-Lindau tumor suppressor protein (pVHL). Human pVHL binds to a short HIF-derived peptide when a conserved proline residue at the core of this peptide is hydroxylated. This protein modifiation may play a key role in mammalian oxygen sensing

Substrates: hypoxia-inducible factor (HIF) is a transcriptional complex that plays a central role in the regulation of gene expression by oxygen. In oxygenated and iron replete cells, HIF-alpha subunits are rapidly destroyed by a mechanism that involves ubiquitylation by the von Hippel-Lindau tumor suppressor (pVHL) E3 ligase complex. This process is suppressed by hypoxia and iron chelation, allowing transcriptional activation. The interaction between human pVHL and a specific domain of the HIF-1alpha subunit is regulated through hydroxylation of a proline residue (HIF-1alpha P564) by HIF-alpha prolyl-hydroxylase (HIF-PH). HIF-PH functions directly as a cellular oxygen sensor

hypoxia-inducible factor-L-proline + 2-oxoglutarate + O2
hypoxia-inducible factor-(4R)-4-hydroxy-L-proline + succinate + CO2
Substrates: mammalian cells respond to changes in oxygen availability through a conserved pathway that is regulated by the hypoxia-inducible factor (HIF). The alpha subunit of the hypoxia-inducible factor is targeted for degradation under normoxic conditions by a ubiquitin-ligase complex that recognizes a hydroxylated proline residue in hypoxia-inducible factor. HIF prolyl hydroxylase is responsible for this posttranslational modification

macrophages deficient in PHD3 have decreased levels of stress-induced apoptosis.

malfunction
PHD2 knockdown causes a marked reduction of erythropoietin (EPO) production. HIF seems not to be involved in this process
malfunction
the gene expression of p50 is reduced in the PHD2 knockdown cells, while the protein amount and the subcellular distribution of p65 are not changed in the PHD2 knockdown cells.

physiological function
-
HIF (hypoxia-inducible factor) is a transcription factor that plays a pivotal role in cellular adaptation to changes in oxygen availability. In the presence of oxygen, HIF is targeted for destruction by an E3 ubiquitin ligase containing the von Hippel-Lindau tumor suppressor protein (pVHL). Human pVHL binds to a short HIF-derived peptide when a conserved proline residue at the core of this peptide is hydroxylated. This protein modifiation may play a key role in mammalian oxygen sensing
physiological function
-
hypoxia-inducible factor (HIF) is a transcriptional complex that plays a central role in the regulation of gene expression by oxygen. In oxygenated and iron replete cells, HIF-alpha subunits are rapidly destroyed by a mechanism that involves ubiquitylation by the von Hippel-Lindau tumor suppressor (pVHL) E3 ligase complex. This process is suppressed by hypoxia and iron chelation, allowing transcriptional activation. The interaction between human pVHL and a specific domain of the HIF-1alpha subunit is regulated through hydroxylation of a proline residue (HIF-1alpha P564) by HIF-alpha prolyl-hydroxylase (HIF-PH). HIF-PH functions directly as a cellular oxygen sensor. Exposure of cells to dimethyl-oxalylglycine, that penetrates cells readily, results in rapid induction of HIF-1alpha
physiological function
in cultured mammalian cells, inappropriate accumulation of hypoxia-inducible factor caused by forced expression of the hypoxia-inducible factor-1alpha subunit under normoxic conditions is attenuated by coexpression of HIF prolyl hydroxylase. Suppression of HIF prolyl hydroxylase in cultured Drosophila melanogaster cells by RNA interference results in elevated expression of a hypoxia-inducible gene (LDH, encoding lactate dehydrogenase) under normoxic conditions. HIF prolyl hydroxylase is an essential component of the pathway through which cells sense oxygen

physiological function
isoform PHD3 plays important roles in hypoxia response and early embryo development of Megalobrama amblycephala
physiological function
enzyme PHD2 is to mediate the oxygen-dependent degradation of the labile alpha-subunit of hypoxia-inducible factor (HIF). In the erythropoietin (EPO)-producing human HCC cell line HepG2, PHD2 maintains the expression of hepatocyte nuclear factor-4alpha (HNF-4alpha), an important mediator of EPO expression in hepatocytes, by inhibiting the auto-/paracrine signalling of transforming growth factor-beta1. PHD2 also regulates HIF-independent pathways by interacting with other substrates. In HepG2 cells, PHD2 suppresses the activity of TGF-beta1 pathway and consequently maintains the expression of hepatocyte nuclear factor-4alpha (HNF-4alpha), an important transcription factor promoting the erythropoietin (EPO) expression in hepatocytes. PHD2 represents a potential contributing factor for hepatocellular carcinoma-associated erythrocytosis. Erythrocytosis generally leads to elevated blood viscosity and is a significant risk factor for lung artery thromboembolism, a life-threatening condition. The ability of some HCC cells to secrete EPO, a glycoprotein hormone which promotes erythropoiesis, contributes to HCC-associated erythrocytosis
physiological function
oxygen deprivation (hypoxia) is a common feature of solid tumors in advanced stages. The primary cellular transcriptional responses to hypoxia are mainly mediated by the transcription factor hypoxia-inducible factor (HIF). HIF consists of an oxygen-labile alpha-subunit (HIF-1alpha, HIF-2alpha) and a stable beta-subunit (ARNT). Prolyl-4-hydroxylase 2 (PHD2) is an important mediator of the oxygen-dependent degradation of HIF-alpha subunits. Prolyl-4-hydroxylase 2 enhances hypoxia-induced glioblastoma cell death by regulating the gene expression of hypoxia-inducible factor-alpha. In the glioblastoma cells, PHD2 maintains the gene expression of HIF-1alpha in dependence of nuclear factor kappaB and suppresses the gene expression of HIF-2alpha through HIF-1alpha. The PHD2-mediated degradation of HIF-1alpha and HIF-2alpha seems less important. PHD2 maintains the gene expression of the NFkappaB subunit p50 in glioblastoma cells. PHD2 enhances hypoxia-induced glioblastoma cell death by modulating the expression of the HIF target genes glucose transporter 1, vascular endothelial growth factor-A and Bcl-2 binding protein 3. PHD2 inhibits the adaptation of glioblastoma cells to hypoxia by regulating the HIF-alpha subunits in a non-canonical way. But exogenous PHD2 has no impact on the gene expression of HIF-1alpha and HIF-2alpha in glioblastoma cells
physiological function
PHD2 controls the expression of many of the pro-catabolic and inflammatory genes that are known to be involved with the degenerative cascade and matrix breakdown. Prolyl-4-hydroxylase domain protein 2 controls NF-kappaB/p65 transactivation and enhances the catabolic effects of inflammatory cytokines on cells of the nucleus pulposus, regulatory mechanism of PHD2 function and expression under inflammatory conditions in the nucleus pulposus, overview. PHD2 controls TNF-alpha effects by positively regulating NF-kappaB signaling, whereas NF-kappaB mediates cytokine-dependent PHD2 expression. PHD2 and NF-kappaB form a functional circuit that promotes the catabolic effects of TNF-alpha in the intervertebral disc. PHD2 is a potent regulator of the catabolic activities of TNF-alpha, silencing of PHD2 significantly decreases TNF-alpha-induced expression of catabolic markers including SDC4, MMP-3, MMP-13, and ADAMTS5, as well as several inflammatory cytokines and chemokines, while partially restoring aggrecan and collagen II expression

physiological function
the HIF-PHDs (PHD1, PHD2, and PHD3, also known as EGLN2, EGLN1, and EGLN3, respectively) are a family of dioxygenases that use non-mitochondrial molecular oxygen as a cosubstrate in the hydroxylation of two residues, in what is termed the oxygen-dependent degradation domain of the HIFalpha isoform (Pro402 and Pro564 on HIF-1alpha). Hydroxylation of oxygen-dependent degradation domain of the HIFalpha isoform residues Pro402 and Pro564 renders the HIFalpha subunit as a target for the von Hipple Lindau protein, which recruits an E3 ubiquitin ligase complex that ubiquitinates HIF, leading to its proteasomal degradation. This process is prevented in hypoxia, leading to the rapid stabilization of HIFalpha, which is then free to translocate to the nucleus, to bind to HIF1beta/aryl hydrocarbon receptor nuclear translocator, and to form the transcriptionally active HIF complex. Isozyme PHD3 is proposed to play a role in a negative-feedback loop, curtailing the HIF-dependent response in prolonged hypoxia, presumably, to prevent excessive angiogenesis and other adaptive processes
