Western blot shows lysates of human testis tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human ADAM32 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5380) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for ADAM32 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

ADAM32 (a disintegrin and metalloprotease domain 32) is a 90‑100 kDa member of the M12B peptidase family of proteins. It is expressed on sperm found in the testis, epididymis and vas deferens. The human ADAM32 proprecursor is a 771 amino acid (aa) type I transmembrane protein. It contains a 158 aa proregion (aa 17‑174) and a 508 aa extracellular domain (ECD) (aa 175‑682). The ECD contains a nonfunctional metalloprotease domain (aa 186‑383), an integrin-binding disintegrin region (aa 391‑479), a Cys-rich segment (aa 480 - 502) and an EGF-like domain (aa 622‑654). In the testis, mature ADAM32 is approximately 98 kDa in size; in the epididymis, cleavage occurs after the metalloprotease domain to generate a 44 kDa product. There are two potential splice events that show a deletion of aa 306‑401 plus a 53 aa substitution for the N‑terminal 46 amino acids. Over aa 17‑476, human ADAM32 is 66% aa identical to mouse ADAM32.
