ncbi summary :
This gene is a member of the Tre-2/BUB2/CDC16 domain family. The protein encoded by this gene is a Rab-GTPase-activating protein, and contains two phopshotyrosine-binding domains (PTB1 and PTB2), a calmodulin-binding domain (CBD), a Rab-GTPase domain, and multiple AKT phosphomotifs. This protein is thought to play an important role in glucose homeostasis by regulating the insulin-dependent trafficking of the glucose transporter 4 (GLUT4), important for removing glucose from the bloodstream into skeletal muscle and fat tissues. Reduced expression of this gene results in an increase in GLUT4 levels at the plasma membrane, suggesting that this protein is important in intracellular retention of GLUT4 under basal conditions. When exposed to insulin, this protein is phosphorylated, dissociates from GLUT4 vesicles, resulting in increased GLUT4 at the cell surface, and enhanced glucose transport. Phosphorylation of this protein by AKT is required for proper translocation of GLUT4 to the cell surface. Individuals homozygous for a mutation in this gene are at higher risk for type 2 diabetes and have higher levels of circulating glucose and insulin levels after glucose ingestion. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2015]
uniprot summary :
AS160: a widely-expressed Rab GTPase-activating protein which apparently plays a role in mediating insulin action. Phosphorylated by the Ser/Thr protein kinase Akt in response to insulin. Is redistributed from low-density microsomes to the cytosol upon insulin treatment. Insulin stimulation of GLUT4 exocytosis is dependent on AS160. The translocation of GLUT4 from intracellular storage sites to the cell surface functions to stimulate insulin uptake by adipose and muscle tissue. Its expression is decreased by twofold in pancreatic islets in type 2 diabetes patients compared to control subjects; its phosphorylation is impaired in skeletal muscle of type 2 diabetics. The protein is expressed in pancreatic Langerhans islets, including beta cells. Up-regulated in T cells from patients with atopic dermatitis. Two alternatively spliced isoforms have been described. Isoform 2, which promotes GLUT4 translocation at the plasma membrane, is the highest overexpressed in most tissues. Isoform 2 shows a cytoplasmic perinuclear localization in a myoblastic cell line in resting and insulin-stimulated cells Isoform 2 is strongly expressed in adrenal and thyroid gland, and also in lung, kidney, colon, brain and adipose tissue. Isoform 2 is moderately expressed in skeletal muscle. Isoform 1 is highly expressed in skeletal muscle and heart, but was not detectable in the liver or adipose tissue. Protein type: GAPs; GAPs, Rab. Chromosomal Location of Human Ortholog: 13q22.2. Cellular Component: cytoplasmic vesicle membrane; cytoplasm. Biological Process: vesicle-mediated transport; negative regulation of vesicle fusion; cellular response to insulin stimulus. Disease: Diabetes Mellitus, Noninsulin-dependent, 5
