Description
Product Characteristics:
Insulin is a pancreatic hormone that regulates glucose and is involved in the synthesis of protein and fat. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver. Heterodimer of a B chain and an A chain linked by two disulfide bonds.Belongs to the insulin family. The insulin-link growth factors, IGF-I and IGF-II (also desinated somatomedin C and multiplication stimulating activator, respectvely), share approximatly 76 % sequence identity and are 50 % related to pro-insulin.IGF-I and IGF-II are nonglycosylated, single chain proteins of 70 and 76 amino acids in length, respectivelly. IGF-I functions as an autocrine regulator of growth in vaious, whereas the function of IGF-II is less well defined.
Synonyms: ILPR, INS, Insulin A chain, Insulin B chain, Insulin A chain, Insulin precursor, IRDN, Proinsulin, Proinsulin precursor, IDDM2, INS_HUMAN, MODY10.
Target Information: After removal of the precursor signal peptide, proinsulin is post-translationally cleaved into three peptides: the B chain and A chain peptides, which are covalently linked via two disulfide bonds to form insulin, and C-peptide. Binding of insulin to the insulin receptor (INSR) stimulates glucose uptake. A multitude of mutant alleles with phenotypic effects have been identified. There is a read-through gene, INS-IGF2, which overlaps with this gene at the 5' region and with the IGF2 gene at the 3' region. Alternative splicing results in multiple transcript variants.
