Rabbit anti-Human ABCG1 Polyclonal Antibody

Uniprot Id

P45844

Target Species

Human

Target Name

ABCG1

Target Full Name

ATP-binding cassette sub-family G member 1

Target Function

Catalyzes the efflux of phospholipids such as sphingomyelin, cholesterol and its oxygenated derivatives like 7beta-hydroxycholesterol and this transport is coupled to hydrolysis of ATP. The lipid efflux is ALB-dependent. Is an active component of the macrophage lipid export complex. Could also be involved in intracellular lipid transport processes. The role in cellular lipid homeostasis may not be limited to macrophages. Prevents cell death by transporting cytotoxic 7beta-hydroxycholesterol.

Target Subcellular Location

Endoplasmic reticulum membrane; Multi-pass membrane protein. Golgi apparatus membrane; Multi-pass membrane protein. Cell membrane. Note=Predominantly localized in the intracellular compartments mainly associated with the endoplasmic reticulum (ER) and Golgi membranes.

Target Protein Families

ABC transporter superfamily, ABCG family, Eye pigment precursor importer (TC 3.A.1.204) subfamily

Target Tissue Specificity

Expressed in several tissues. Expressed in macrophages; expression is increased in macrophages from patients with Tangier disease.

Target Research Area

Cancer

Target Synonyms

ABCG1; ABC8; WHT1; ATP-binding cassette sub-family G member 1; ATP-binding cassette transporter 8; White protein homolog

Target Background

The 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 White subfamily. It is involved in macrophage cholesterol and phospholipids transport, and may regulate cellular lipid homeostasis in other cell types. Six alternative splice variants have been identified.
