Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 64137 Official Symbol ABCG4
Locus N/A Gene Type protein-coding
Synonyms WHITE2
Full Name ATP-binding cassette, sub-family G (WHITE), member 4
Description ATP-binding cassette, sub-family G (WHITE), member 4
Chromosome 11q23.3
Also Known As ATP-binding cassette, subfamily G, member 4; putative ABC transporter
Summary The protein encoded by this gene is included in 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 and is expressed predominantly in liver tissue. The function has not yet been determined but may involve cholesterol transport. Alternate splice variants have been described but their full length sequences have not been determined. [provided by RefSeq]
