Hydroxylates HIF1A at 'Pro-402' and 'Pro-564'. May function as a cellular oxygen sensor and, under normoxic conditions, may target HIF through the hydroxylation for proteasomal degradation via the von Hippel-Lindau ubiquitination complex. {ECO:0000269|PubMed:17726031}. |2OG-FeII Oxy| |procollagen-proline 4-dioxygenase activity| |peptidyl-proline hydroxylation to 4-hydroxy-L-proline| |peptidyl-proline hydroxylation| |4-hydroxyproline metabolic process| |2-oxoglutarate-dependent dioxygenase activity| |L-ascorbic acid binding| |protein hydroxylation| |regulation of erythrocyte differentiation| |peptidyl-proline modification| |iron ion binding| |cellular modified amino acid metabolic process| |alpha-amino acid metabolic process| |regulation of myeloid cell differentiation| |cellular amino acid metabolic process| |regulation of hemopoiesis| |calcium ion binding| |peptidyl-amino acid modification| |carboxylic acid metabolic process| |endoplasmic reticulum membrane| |oxidation-reduction process| |oxoacid metabolic process| |endoplasmic reticulum| |organic acid metabolic process| |regulation of immune system process| |small molecule metabolic process| |regulation of cell differentiation| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp348|Cyclosporin-A 3μM R07 exp348]]|-1.98| |[[:results:exp19|Etoposide 1μM R00 exp19]]|-1.89| |[[:results:exp20|Etoposide 10μM R00 exp20]]|-1.72| No correlation found to any other genes in chemogenomics.
