A Disintegrin And Metalloprotease (ADAM) proteins belong to the metzincin superfamily of metalloproteases. ADAM proteins are characterized by a highly conserved domain organization that generally includes a prodomain, metalloprotease domain, disintegrin-like domain, cysteine rich domain, EGF-like domain, transmembrane domain and a cytoplasmic domain. The metalloprotease domain is attributed to a process known as ectodomain shedding in which it cleaves at cell surfaces to release the ectodomains of membrane proteins. ADAM proteases are included in MEROPS family M12, subfamily B. (Adapted from FBrf0214506 and FBrf0211961).
Notes on Group
Although listed in FBrf0214506 as an ADAM, mmd lacks key catalytic residues and is included in the 'M12 NON_PEPTIDASE HOMOLOGS' gene group.
