PubMed PubMed Product Detail The protein encoded by this gene belongs to a highly conserved cAMP-regulated phosphoprotein (ARPP) family. This protein was identified as an endogenous ligand for the sulfonylurea receptor, ABCC8/SUR1. ABCC8 is the regulatory subunit of the ATP-sensitive potassium (KATP) channel, which is located on the plasma membrane of pancreatic beta cells and plays a key role in the control of insulin release from pancreatic beta cells. This protein is thought to be an endogenous regulator of KATP channels. In vitro studies have demonstrated that this protein modulates insulin secretion through the interaction with KATP channel, and this gene has been proposed as a candidate gene for type 2 diabetes. At least eight alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008]
Function:
ENSA (Alpha endosulfine) is expressed in a wide range of tissues including muscle, brain, and endocrine tissues. The recombinant protein inhibits binding of labeled glibenclamide to beta cell membranes. It also inhibits cloned K(ATP) channel currents and thereby stimulates insulin secretion. It was proposed that endosulfine is an endogenous regulator of the K(ATP) channel, which has a key role in the control of insulin release and, more generally, couples cell metabolism to electrical activity.
Subunit:
Interacts (when phosphorylated at Ser-67) with PPP2R2D. Interacts with ABCC8. Interacts with SNCA; interaction is disrupted when phosphorylated at Ser-109.
Subcellular Location:
Cytoplasmic
Tissue Specificity:
Widely expressed with high levels in skeletal muscle and brain and lower levels in the pancreas.
Post-translational modifications:
Phosphorylation at Ser-67 by GWL during mitosis is essential for interaction with PPP2R2D (PR55-delta) and subsequent inactivation of PP2A (By similarity). Phosphorylated by PKA.
Similarity:
Belongs to the endosulfine family.
