metabolism
O87725
catalyzes step 7 in the ornithine fermentation pathway
physiological function
-
treatment with oxidized low-density lipoproteins decreases the cell number per field and causes the cells to round up. Knock-down of proline oxidase via small interfering RNA further reduces viability of cancer cells treated with oxidized low-density lipoproteins, decreases oxidized low-density lipoproteins-associated reactive oxygen species generation, decreases autophagy measured via beclin-1 protein level and light-chain 3 protein-I into LC3-II conversion. Single proline oxidase overexpression is sufficient to activate autophagy. It leads to autophagosomes accumulation and increases conversion of LC3-I into LC3-II.Beclin-1 gene expression is directly dependent on proline oxidase catalytic activity, namely the generation of prloine-oxidase-dependent superoxide

LITERATURE
upregulated micro-RNA miR-23b* in renal cancer is an important regulator of POX. Ectopic overexpression of miR-23b* in normal renal cells results in striking downregulation of POX, whereas POX expression increases markedly when endogenous miR-23b* is knocked down by its antagomirs in renal cancer cells

identification of a single homozygous region near the telomere of chromosome 17 in a cohort of patients with cutis laxa type 2. The single nucleotide change leads to a missense mutation adjacent to a slice junction in the gene encoding pyrroline-5-carboxylate reductase 1 which results in exon skipping and leads to deletion of reductase functional domain-coding region and an obligatory downstream frameshift

micro-RNA miR-23b*, by targeting POX, may function as an oncogene. Pairs of human renal carcinoma and normal tissues show a negative correlation between miR-23b* and POX protein expression, providing its clinical corroboration. Ectopic overexpression of miR-23b* in normal renal cells results in striking downregulation of POX, whereas POX expression increases markedly when endogenous miR-23b* is knocked down by its antagomirs in renal cancer cells

pyrroline-5-carboxylate reductase is related to virulence of Mycobacterium tuberculosis
