Anti-CEMIP Antibody, clone PW-3

Cell migration-inducing and hyaluronan-binding protein (UniProt: Q8WUJ3; also known as EC:3.2.1.35, CCSP1, CEMIP) is encoded by the CEMIP (also known as KIAA1199) gene (Gene ID: 57214) in human. CEMIP is highly glycosylated protein that is widely distributed in the cytoplasm and is localized in endoplasmic reticulum, endosomes, cell membrane, and in exosomes. It is also abundantly secreted. It is synthesized with a signal peptide (aa 1-30) that is essential for its proper translocation, hyaluronic acid (HA) degradation activity, and secretion. It mediates depolymerization of HA via the cell membrane-associated clathrin-coated pit endocytic pathway. It hydrolyzes high molecular weight HA to produce an intermediate-sized product, a process that may occur through rapid vesicle endocytosis and recycling without intracytoplasmic accumulation or digestion in lysosomes. CEMIP contains two GG domains, one G8 domain (aa 44-166), and four PbH1 domains (aa 572-819). The G8 domain contains eight conserved glycine residues and is reported to bind to Annexin 1 that enables it to adhere to cell membrane in Annexin 1 positive cells. The two GG domains are composed of seven β-strands and two helices and are located N-terminally after the G8 domain. Each of the four PbH1 domains contain 22 to 23 amino acids and function in polysaccharide hydrolysis. Amino acids sequence 295-591, also known as the B domain, is essential for its retention in the endoplasmic reticulum. CEMIP expression is strongly upregulated in many types of cancer and its higher levels are associated with poor prognosis in cancer patients. Higher expression of CEMIP is reported in ductal carcinoma and invasive breast cancer cells, gastric cancers, and in colon adenocarcinomas. It is considered as a potential blood-borne biomarker for colorectal cancers. The knockdown of CEMIP gene has been shown to significantly reduce metastasis to the lung, liver, and various other organs. (Ref.: Domanegg, K., et al (2022).
