Vitamin K is a required co-factor for carboxylation of glutamic acid residues by vitamin K-dependent gamma-carboxylase in blood-clotting enzymes. Allelic variation in this gene is associated with vitamin k-dependent clotting factors combined deficiency of 2, and increased resistance or sensitivity to warfarin, an inhibitor of vitamin K epoxide reductase. Pseudogenes of this gene are located on chromosomes 1 and X. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]. * **UniProt Summary**: Involved in vitamin K metabolism. Catalytic subunit of the vitamin K epoxide reductase (VKOR) complex which reduces inactive vitamin K 2,3-epoxide to active vitamin K. Vitamin K is required for the gamma-carboxylation of various proteins, including clotting factors, and is required for normal blood coagulation, but also for normal bone development. {ECO:0000269|PubMed:14765194, ECO:0000269|PubMed:14765195, ECO:0000269|PubMed:15879509, ECO:0000269|PubMed:16270630, ECO:0000269|PubMed:20978134, ECO:0000269|PubMed:22923610}. |VKOR| |vitamin-K-epoxide reductase (warfarin-insensitive) activity| |vitamin-K-epoxide reductase (warfarin-sensitive) activity| |peptidyl-glutamic acid carboxylation| |protein carboxylation| |vitamin K metabolic process| |quinone binding| |peptidyl-glutamic acid modification| |fat-soluble vitamin metabolic process| |regulation of blood coagulation| |regulation of hemostasis| |regulation of coagulation| |vitamin metabolic process| |regulation of wound healing| |regulation of response to wounding| |bone development| |blood coagulation| |coagulation| |hemostasis| |response to antibiotic| |wound healing| |skeletal system development| |regulation of body fluid levels| |drug metabolic process| |response to wounding| |peptidyl-amino acid modification| |response to organic cyclic compound| |endoplasmic reticulum membrane| |oxidation-reduction process| |response to organonitrogen compound| |endoplasmic reticulum| |response to nitrogen compound| |regulation of response to external stimulus| |regulation of response to stress| |small molecule metabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp145|PNU96415E 10μM R03 exp145]]|-1.73| |[[:results:exp317|Geldanamycin 0.015 to 0.05μM on day4 R07 exp317]]|1.76| |[[:results:exp348|Cyclosporin-A 3μM R07 exp348]]|1.89| No correlation found to any other genes in chemogenomics.
