Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 23457 Official Symbol ABCB9
Locus N/A Gene Type protein-coding
Synonyms EST122234; KIAA1520; TAPL
Full Name ATP-binding cassette, sub-family B (MDR/TAP), member 9
Description ATP-binding cassette, sub-family B (MDR/TAP), member 9
Chromosome 12q24
Also Known As
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, this protein may play a role in lysosomes. Alternative splicing of this gene results in distinct isoforms which are likely to have different substrate specifications. [provided by RefSeq]
