ALB（albumin），癌症关联基因，基因ID：213，这个基因编码人类血液中最丰富的蛋白质。这种蛋白质在调节血浆胶体渗透压中发挥作用，并作为一种载体蛋白，用于多种内源性分子，包括激素、脂肪酸、代谢物以及外源性药物。此外，该蛋白具有广泛的底物特异性和酯酶样活性。编码的前蛋白经蛋白质水解处理生成成熟蛋白。从这种蛋白质衍生的肽epi-x4是cxcr4趋化因子受体的内源性抑制剂。[由RefSeq提供，2016年7月]This gene encodes the most abundant protein in human blood. This protein functions in the regulation of blood plasma colloid osmotic pressure and acts as a carrier protein for a wide range of endogenous molecules including hormones， fatty acids， and metabolites， as well as exogenous drugs. Additionally， this protein exhibits an esterase-like activity with broad substrate specificity. The encoded preproprotein is proteolytically processed to generate the mature protein. A peptide derived from this protein， EPI-X4， is an endogenous inhibitor of the CXCR4 chemokine receptor. [provided by RefSeq， Jul 2016]。
