[ - ] NCBI Entrez Gene

Gene ID 26154 Official Symbol ABCA12
Locus N/A Gene Type protein-coding
Synonyms DKFZp434G232; FLJ41584; ICR2B; LI2
Full Name ATP-binding cassette, sub-family A (ABC1), member 12
Description ATP-binding cassette, sub-family A (ABC1), member 12
Chromosome 2q34
Also Known As ATP-binding cassette, sub-family A, member 12; ichthyosis congenita II, lamellar ichthyosis B
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 intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White). This encoded protein is a member of the ABC1 subfamily, which is the only major ABC subfamily found exclusively in multicellular eukaryotes. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq]
