About ABCG4

Cytogenetic location: 11q23.3 Genomic coordinates (GRCh38): 11:119,149,052-119,162,666 (from NCBI)

This gene has 6 transcripts (splice variants), 282 orthologues and 4 paralogues. Biased expression in testis (RPKM 2.4), brain (RPKM 2.0) and 8 other tissues.

Summary

The protein encoded by this gene is a member of the ATP-binding cassette (ABC) transporter superfamily. 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). The encoded protein is a member of the White subfamily and plays an important role in cellular Cholesterol homeostasis. This protein functions as either a homodimer or as a heterodimer with another ABC subfamily protein such as ABCG1. [provided by RefSeq, Jan 2017]
