Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 26357 Official Symbol Abcg2
Locus N/A Gene Type protein-coding
Synonyms ABC15; ABCP; AI428558; BCRP; Bcrp1; MXR; MXR1
Full Name ATP-binding cassette, sub-family G (WHITE), member 2
Description ATP-binding cassette, sub-family G (WHITE), member 2
Chromosome 6 B3|6 28.5 cM
Also Known As ATP-binding cassette, sub-family G, member 2; OTTMUSP00000025071; OTTMUSP00000025391; mitoxantrone resistance protein 1
Summary The membrane-associated 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. Alternatively referred to as a breast cancer resistance protein, the human protein functions as a xenobiotic transporter which may play a major role in multi-drug resistance. This protein likely serves as a cellular defense mechanism in response to mitoxantrone and anthracycline exposure. [provided by RefSeq]
