Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 11194 Official Symbol ABCB8
Locus N/A Gene Type protein-coding
Synonyms EST328128; M-ABC1; MABC1
Full Name ATP-binding cassette, sub-family B (MDR/TAP), member 8
Description ATP-binding cassette, sub-family B (MDR/TAP), member 8
Chromosome 7q36
Also Known As ATP-binding cassette, sub-family B, member 8; mitochondrial ABC protein
Summary The membrane-associated 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 MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance as well as antigen presentation. The function of this half-transporter has not yet been determined; however, it may involve the compartmentalization and transport of heme, as well as peptides, from the mitochondria to the nucleus and cytosol. This protein may also play a role in the transport of phospholipids into mitochondrial membranes. [provided by RefSeq]
