Entrez Gene Summary for ABCG2 Gene

  • The membrane-associated protein encoded by this gene is included in 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. Alternatively referred to as a breast cancer resistance protein, this protein functions as a xenobiotic transporter which may play a major role in multi-drug resistance. It likely serves as a cellular defense mechanism in response to mitoxantrone and anthracycline exposure. Significant expression of this protein has been observed in the placenta, which may suggest a potential role for this molecule in placenta tissue. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

UniProtKB/Swiss-Prot Summary for ABCG2 Gene

  • Broad substrate specificity ATP-dependent transporter of the ATP-binding cassette (ABC) family that actively extrudes a wide variety of physiological compounds, dietary toxins and xenobiotics from cells (PubMed:11306452, PubMed:12958161, PubMed:19506252, PubMed:20705604, PubMed:28554189, PubMed:30405239, PubMed:31003562). Involved in porphyrin homeostasis, mediating the export of protoporphyrin IX (PPIX) from both mitochondria to cytosol and cytosol to extracellular space, it also functions in the cellular export of heme (PubMed:20705604, PubMed:23189181). Also mediates the efflux of sphingosine-1-P from cells (PubMed:20110355). Acts as a urate exporter functioning in both renal and extrarenal urate excretion (PubMed:19506252, PubMed:20368174, PubMed:22132962, PubMed:31003562). In kidney, it also functions as a physiological exporter of the uremic toxin indoxyl sulfate (By similarity). Also involved in the excretion of steroids like estrone 3-sulfate/E1S, 3beta-sulfooxy-androst-5-en-17-one/DHEAS, and other sulfate conjugates (PubMed:12682043, PubMed:28554189, PubMed:30405239). Mediates the secretion of the riboflavin and biotin vitamins into milk (By similarity). Extrudes pheophorbide a, a phototoxic porphyrin catabolite of chlorophyll, reducing its bioavailability (By similarity). Plays an important role in the exclusion of xenobiotics from the brain (Probable). It confers to cells a resistance to multiple drugs and other xenobiotics including mitoxantrone, pheophorbide, camptothecin, methotrexate, azidothymidine, and the anthracyclines daunorubicin and doxorubicin, through the control of their efflux (PubMed:11306452, PubMed:12477054, PubMed:15670731, PubMed:18056989, PubMed:31254042). In placenta, it limits the penetration of drugs from the maternal plasma into the fetus (By similarity). May play a role in early stem cell self-renewal by blocking differentiation (By similarity).

Post-translational modifications for ABCG2 Gene

  • N-glycosylated (PubMed:15807535, PubMed:23189181). Glycosylation-deficient ABCG2 is normally expressed and functional.
  • Phosphorylated. Phosphorylation at Thr-362 by PIM1 is induced by drugs like mitoxantrone and is associated with cells increased drug resistance. It regulates the localization to the plasma membrane, the homooligomerization and therefore, the activity of the transporter.
  • Glycosylation at Asn596
  • Modification sites at PhosphoSitePlus

Polymorphic Variants from UniProtKB/Swiss-Prot for ABCG2 Gene

ABCG2_HUMAN-Q9UNQ0
Genetic variations in ABCG2 define the blood group Junior system (JR) [MIM:614490]. Individuals with Jr(a-) blood group lack the Jr(a) antigen on their red blood cells. These individuals may have anti-Jr(a) antibodies in their serum, which can cause transfusion reactions or hemolytic disease of the fetus or newborn. Although the clinical significance of the Jr(a-) blood group has been controversial, severe fatal hemolytic disease of the newborn has been reported. The Jr(a-) phenotype has a higher frequency in individuals of Asian descent, compared to those of European descent. The Jr(a-) phenotype is inherited as an autosomal recessive trait.
ABCG2_HUMAN-Q9UNQ0
Genetic variations in ABCG2 influence the variance in serum uric acid concentrations and define the serum uric acid concentration quantitative trait locus 1 (UAQTL1) [MIM:138900]. Excess serum accumulation of uric acid can lead to the development of gout, a common disorder characterized by tissue deposition of monosodium urate crystals as a consequence of hyperuricemia (PubMed:18834626, PubMed:19506252, PubMed:20368174).
