Protein attributes

Sequence length	765 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Metalloprotease involved in sperm function, possibly by modulating the processes of fertilization and early embryonic development. Degrades a broad variety of small peptides with a preference for peptides shorter than 3 kDa containing neutral bulky aliphatic or aromatic amino acid residues. Shares the same substrate specificiy with MME and cleaves peptides at the same amide bond. Ref.1 Ref.3
Catalytic activity	Preferential cleavage of polypeptides between hydrophobic residues, particularly with Phe or Tyr at P1'.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Enzyme regulation	Inhibited by thiorphan and phosphoramidon. Ref.3
Subcellular location	Membrane; Single-pass type II membrane protein. Secreted. Note: A secreted form produced by proteollytic cleavage also exists. Ref.1
Tissue specificity	Highly expressed in testis. Also expressed in ovary. Weakly or not expressed in brain, lung, heart, liver, kidney, adrenal gland and intestine. Ref.1
Post-translational modification	N-glycosylated. Ref.1 Ref.2
Disruption phenotype	Mice are viable and develop normally. However, males produce smaller litters, indicating specific male fertility problems. Ref.5
Sequence similarities	Belongs to the peptidase M13 family.
Biophysicochemical properties	Kinetic parameters: KM=18 µM for D-Ala(2)-Leu(5)-enkephalin
