CC   -!- FUNCTION: Sperm surface membrane protein that may be involved in sperm-
CC       egg plasma membrane adhesion and fusion during fertilization. It could
CC       be a potential receptor for the egg oligosaccharide residue N-
CC       acetylglucosamine, which is present in the extracellular matrix over
CC       the egg plasma membrane (By similarity).
CC       {ECO:0000250|UniProtKB:Q8IXA5}.
CC   -!- MISCELLANEOUS: On the 2D-gel the determined pI of this protein is: 5.3,
CC       its MW is: 16.8 kDa. {ECO:0000269|PubMed:12065460}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 22 family. {ECO:0000255}.
CC   -!- CAUTION: May lack the conserved Glu and Asp residues essential for
CC       activity. {ECO:0000250|UniProtKB:Q8IXA5, ECO:0000305}.
