LITERATURE
SOURCE
pantetheinase is an ectoenzyme that is attached to the outer plasma membrane by a glycosylphosphatidylinositol (GPI) anchor. GPI anchors consist of three domains: a phosphoethanolamine linker that attaches to the C terminal end of the target protein, a conserved glycan core and a phospholipid tail for anchoring to the lipid membrane

LITERATURE
malfunction
metabolism
physiological function
malfunction
-
vanin 1 knockout mice display an enhanced resistance to oxidative stress and show down-regulated tissue inflammation in response to oxidative stress. Vanin knockout mice exhibit a loss of cysteamine-mediated inhibition of peroxisome proliferator-activated receptor gamma. Vanin 1 deficient islets are twice as susceptible to cell death as wild type cells
physiological function
-
vanin plays a role in inflammation, oxidative stress, cell migration and numerous diseases including cardiovascular disease (increased vanin 1 activity has a protective effect against cardiovascular disease). Vanin 1 has a cytoprotective effect against type 1 diabetes in islet cells. Vanin 1 is a central regulator of not only stress responses via production of cysteamine but also lipid biosynthesis by controlling the flux through the fatty acid and/or cholesterol biosynthetic pathways

EXPRESSION
ORGANISM

LITERATURE
expression of pantetheinase is controlled by the Vnn1 gene and is upregulated in response to free fatty acids, PPAR activation or oxidative stress. PPARalpha-mediated upregulation of Vnn1 translates to enhanced pantetheinase activity in vivo
inactivation of vnn1 on the development of fibrosis, endothelial alterations, and immunological activation in mice with HOCl- and bleomycin-induced systemic sclerosis (SSc)
PPAR-alpha KO mice show a negligible liver vnn1 expression, even after stimulation with various agonists
starvation-induced pantetheinase upregulation
upon administration of the PPAR-alpha agonists fenofibrate, clofibrate, or Wy-14,643, gene vnn1 expression is increased. The transcription of vnn1 itself is activated by PPAR-alpha coactivator 1 (PGC-1) in complex with the hepatocyte nuclear factor-4alpha (HNF-4alpha). In turn, this complex is mediated by the Akt signaling pathway
