This gene encodes the catalytic subunit of the vitamin K epoxide reductase complex, which is responsible for the reduction of inactive vitamin K 2,3-epoxide to active vitamin K in the endoplasmic reticulum membrane. 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 ... See more...

Entrez Gene Summary for VKORC1 Gene

  • This gene encodes the catalytic subunit of the vitamin K epoxide reductase complex, which is responsible for the reduction of inactive vitamin K 2,3-epoxide to active vitamin K in the endoplasmic reticulum membrane. 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]

VKOR1_HUMAN :
  • The number of transmembrane domains and the membrane topology are controversial; supporting evidence is available both for models with three transmembrane domains (PubMed:15716279 and PubMed:22923610) and four transmembrane domains (PubMed:20696932 and PubMed:20978134). According to PubMed:15716279 and PubMed:22923610 the N-terminus of the protein is in the endoplasmic reticulum lumen, while the C-terminus is in the cytosol, which is in favor of three transmembrane domains. According to PubMed:20696932, both N-terminus and C-terminus are in the cytosol, indicating the presence of four transmembrane domains. Besides, the 3D-structure of a bacterial ortholog shows four transmembrane domains. Moreover, proteins that reside in the endoplasmic reticulum lumen can catalyze the reduction of the active site cysteines, possibly via Cys-43 and Cys-51 (PubMed:20696932 and PubMed:20978134), but less efficiently than the synthetic compound dithiothreitol (in vitro). Location of Cys-43 and Cys-51 in the endoplasmic reticulum lumen would be in agreement with four transmembrane domains. Again, these data are controversial, and papers do not agree on the effects of mutating Cys-43 and Cys-51, probably because of differences in the assay systems.
  • Belongs to the VKOR family.
