Protein attributes

Sequence length	473 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	Hydrolyzes high molecular weight hyaluronic acid to produce an intermediate-sized product which is further hydrolyzed by sperm hyaluronidase to give small oligosaccharides. Displays very low levels of activity. Associates with and negatively regulates MST1R By similarity.
Catalytic activity	Random hydrolysis of (1->4)-linkages between N-acetyl-beta-D-glucosamine and D-glucuronate residues in hyaluronate.
Subunit structure	Interacts with MST1R By similarity.
Subcellular location	Cell membrane; Lipid-anchor › GPI-anchor By similarity.
Sequence similarities	Belongs to the glycosyl hydrolase 56 family. Contains 1 EGF-like domain.
