Rabbit anti-Human ABCB7 Polyclonal Antibody

Uniprot Id

O75027

Target Species

Human

Target Name

ABCB7

Target Full Name

Iron-sulfur clusters transporter ABCB7, mitochondrial

Target Function

Exports glutathione-coordinated iron-sulfur clusters such as [2Fe-2S]-(GS)4 cluster from the mitochondria to the cytosol in an ATP-dependent manner allowing the assembly of the cytosolic iron-sulfur (Fe/S) cluster-containing proteins and participates in iron homeostasis. Moreover, through a functional complex formed of ABCB7, FECH and ABCB10, also plays a role in the cellular iron homeostasis, mitochondrial function and heme biosynthesis. In cardiomyocytes, regulates cellular iron homeostasis and cellular reactive oxygen species (ROS) levels through its interaction with COX4I1. May also play a role in hematopoiesis.

Target Involvement

Anemia, sideroblastic, spinocerebellar ataxia (ASAT)

Target Subcellular Location

Mitochondrion inner membrane; Multi-pass membrane protein.

Target Protein Families

ABC transporter superfamily, ABCB family, Heavy Metal importer (TC 3.A.1.210) subfamily

Target Background

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.
