General annotation (Comments)

Function

Involved in sperm-egg adhesion. Upon fertilization sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are embedded in a matrix containing hyaluronic acid which is formed prior to ovulation. This protein aids in penetrating the layer of cumulus cells by digesting hyaluronic acid.

Catalytic activity

Random hydrolysis of (1->4)-linkages between N-acetyl-beta-D-glucosamine and D-glucuronate residues in hyaluronate.

Subcellular location

Cell membrane; Lipid-anchorGPI-anchor.

Tissue specificity

Testis.

Sequence similarities

Belongs to the glycosyl hydrolase 56 family.
