Recombinant human ABP1/AOC1 protein

ABP1, also known as diamine oxidase (DAO) and amine oxidase copper domain-containing protein 1 (AOC1), is a member of the copper-containing amine oxidase family. This enzyme catalyzes the oxidation of a wide range of biogenic amines including many neurotransmitters, histamine and xenobiotic amines. It has an important role in the catabolism of histamine and other bioactive polyamines. Deficiencies in ABP1 can result in histaminosis or dietary histamine intolerance. This protein is also contributed to Tumor Progression by Promoting the AKT and EMT Pathways in Gastric Cancer. Recombinant human AOC1, fused to His-tag at C-terminus, was expressed in HEK293 cell and purified by using conventional chromatography techniques.
