Comments
  • FUNCTION: May be involved in sperm maturation and/or fertilization. May also be involved in epithelia functions associated with establishing and maintaining gradients of ions or nutrients.
  • COFACTOR: Binds 1 zinc ion per subunit (Potential).
  • SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
  • DOMAIN: A tripeptide motif (VGE) within disintegrin-like domain could be involved in the binding to egg integrin receptor and thus could mediate sperm/egg binding.
  • DOMAIN: The cysteine-rich domain encodes putative cell-fusion peptides, which could be involved in sperm-egg fusion.
  • 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.
  • PTM: Has no obvious cleavage site for furin endopeptidase, suggesting that the proteolytic processing is regulated.
  • MISCELLANEOUS: May be the functional equivalent of ADAM 1/fertilin alpha which is a pseudogene in human.
  • SIMILARITY: Contains 1 disintegrin domain.
  • SIMILARITY: Contains 1 EGF-like domain.
  • SIMILARITY: Contains 1 peptidase M12B domain [view classification].
