MyBioSource.com's ABCG2 Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: ELISA, Immunohistochemistry, and Western Blot.
Description
Function: High-capacity urate exporter functioning in both renal and extrarenal urate excretion. Plays a role in porphyrin homeostasis as it is able to mediates the export of protoporhyrin IX (PPIX) both from mitochondria to cytosol and from cytosol to extracellular space, and cellular export of hemin, and heme. Xenobiotic transporter that may play an important role in the exclusion of xenobiotics from the brain. Appears to play a major role in the multidrug resistance phenotype of several cancer cell lines. Implicated in the efflux of numerous drugs and xenobiotics: mitoxantrone, the photosensitizer pheophorbide, camptothecin, methotrexate, azidothymidine (AZT), and the anthracyclines daunorubicin and doxorubicin.
Subunit Structure: Monomer under reducing conditions, the minimal functional units is a homodimer; disulfide-linked, but the major oligomeric form in plasma membranes is a homotetramer with possibility of higher order oligomerization up to homododecamers.
Post-translational Modifications: Glycosylation-deficient ABCG2 is normally expressed and functional.
Similarity: The extracellular loop 3 (ECL3) is involved in binding porphyrins and transfer them to other carriers, probably albumin. Belongs to the ABC transporter superfamily. ABCG family. Eye pigment precursor importer (TC 3.A.1.204) subfamily
