Protein attributes

Sequence length	1018 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Plays an important role in the early step of spermatogenesis.
Catalytic activity	Hydrolysis of terminal, non-reducing alpha-D-mannose residues in alpha-D-mannosides.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Subcellular location	Secreted.
Tissue specificity	Mainly expressed in the narrow region between the caput and corpus epididymis.
Developmental stage	Specifically expressed in type A spermatogonia at stages IX-XI of spermatogenesis. Detected there until the cell developed into type B spermatogonia.
Sequence similarities	Belongs to the glycosyl hydrolase 38 family.
