ENSA Polyclonal Antibody, AbBy Fluor™ 488 Conjugated

Sulfonylureas are a class of drugs commonly used in the management of noninsulin-dependent diabetes mellitus. ENSA/ARPP-19, also known as ARPP-19e, is a 121 amino acid protein that localizes to the cytoplasm and belongs to the endosulfine family. ENSA/ARPP-19 is an endogenous regulator of the _-cell K (ATP) channels and reduces K (ATP) channel currents by inhibiting sulfonylurea from binding to the receptor thereby stimulating insulin secretion by pancreatic _ cells. It is suggested that ENSA/ARPP-19 expression is decreased in brains of both Alzheimer's disease (AD) and Down's syndrome patients. Widely expressed with high levels in skeletal muscle and brain and lower levels in pancreas, ENSA/ARPP-19 is phosphorylated by PKA and exists as eight alternatively spliced isoforms. ENSA/ARPP-19 is encoded by a gene located on human chromosome 1q21.3.
