We have previously reported that two trypsin-like enzymes, acrosin and spermosin, play key roles in sperm penetration through the… Expand

Ascidian eggs are surrounded by a noncellular layer and two cellular layers, which are penetrated by sperm. Three sperm surface… Expand

Two types of trypsin-like proteases, spermosin and acrosin, have been highly purified from spermatozoa of the ascidian… Expand

In order to elucidate the role of spermosin (a novel sperm trypsin-like protease) in ascidian fertilization, we developed an… Expand

In order to investigate systematically the substrate or subsite specificity of two sperm proteases; acrosin and spermosin (a… Expand

Among various protease inhibitors, chymostatin (an inhibitor of sperm chymotrypsin-like protease) strongly inhibited the binding… Expand
