cofactor:Binds 1 zinc ion per subunit.,domain:The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.,function:May be involved in spermatogenesis and fertilization.,similarity:Contains 1 disintegrin domain.,similarity:Contains 1 EGF-like domain.,similarity:Contains 1 peptidase M12B domain.,tissue specificity:Expressed specifically in testis.,
Late endosome membrane ; Single-pass type I membrane protein .
Expressed in brain neurons (at protein level) (PubMed:27333034). Expressed in testis (PubMed:10512762).
