About ABCG8

Cytogenetic location: 2p21 Genomic coordinates (GRCh38): 2:43,838,971-43,882,988 (from NCBI)

This gene has 3 transcripts (splice variants), 202 orthologues, 4 paralogues and is associated with 5 phenotypes. Biased expression in small intestine (RPKM 17.4), duodenum (RPKM 17.0) and 1 other tissue.

Summary

The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the White subfamily. The protein encoded by this gene functions to exclude non-cholesterol sterol entry at the intestinal level, promote excretion of Cholesterol and sterols into bile, and to facilitate transport of sterols back into the intestinal lumen. It is expressed in a tissue-specific manner in the liver, intestine, and gallbladder. This gene is tandemly arrayed on chromosome 2, in a head-to-head orientation with family member ABCG5. Mutations in this gene may contribute to sterol accumulation and atherosclerosis, and have been observed in patients with sitosterolemia. [provided by RefSeq, Jul 2008]
