Summaries for ABCB7 Gene

Entrez Gene Summary for ABCB7 Gene

  • 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. This gene encodes a half-transporter involved in the transport of heme from the mitochondria to the cytosol. With iron/sulfur cluster precursors as its substrates, this protein may play a role in metal homeostasis. Mutations in this gene have been associated with mitochondrial iron accumulation and isodicentric (X)(q13) and sideroblastic anemia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2012]

GeneCards Summary for ABCB7 Gene

ABCB7 (ATP-Binding Cassette, Sub-Family B (MDR/TAP), Member 7) is a Protein Coding gene. Diseases associated with ABCB7 include anemia, sideroblastic, with ataxia and x-linked sideroblastic anemia with ataxia. Among its related pathways are Metabolism and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include ATPase activity, coupled to transmembrane movement of substances and heme transporter activity. An important paralog of this gene is ABCB6.
