Description
VAP-1 is a type II membrane cell adhesion protein belonging to the copper/topaquinone oxidase family. It is primarily expressed on the high endothelial venules of peripheral lymph nodes and on hepatic endothelia. VAP-1 can catalyze the oxidative deamination of low molecular weight amines, and plays an important role in the migration of lymphocytes to inflamed tissue. Inhibition of VAP-1 can protect against inflammation-related damage to certain injured tissues. Additionally, VAP-1 can function as a significant prognostic marker for certain cancers and cardiovascular diseases. Recombinant Human VAP-1 is a mixture of monomeric and disulfide-linked homodimeric forms of a 737 amino acid polypeptide, corresponding to amino acids 27 to 763 of the VAP-1 precursor. The calculated molecular weight of Recombinant Human VAP-1 is 81.8 kDa.
