CPAMD7, or CD109 molecule, is a human gene encoded by CD109. It may also be known as: CD109 antigen; 150 kDa TGF-beta-1-binding protein; C3 and PZP-like alpha-2-macroglobulin domain-containing protein 7; Platelet-specific Gov antigen; p180; r150; CD antigen CD109. The encoded protein has an amino acid length of 1445 and a mass of 161.7 kDa. Other isoforms may exist. CPAMD7 is a member of the Protease inhibitor I39 (alpha-2-macroglobulin) family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
