pubmed-article:1281543 | pubmed:abstractText | A 95-kDa mouse sperm protein has been previously identified as a putative receptor involved in the sperm-egg interactions that lead to fertilization. The ligand for this receptor is the zona pellucida glycoprotein ZP3. This constituent of the oocyte-specific extracellular matrix mediates not only sperm binding to the zona but also triggers acrosomal exocytosis. The latter, also termed the acrosome reaction, is a key regulatory event upon which fertilization is absolutely dependent. Previously, we showed that the 95-kDa protein that binds ZP3 is a substrate for tyrosine kinase, and its phosphotyrosine content increases after sperm-zona pellucida binding. Here, we show the presence of protein tyrosine kinase activity in sperm plasma membranes and in electroeluted 95-kDa protein. The tyrosine kinase activity of the isolated protein is stimulated by solubilized zona pellucida and inhibited by tyrphostin RG-50864, a membrane-permeable tyrosine kinase inhibitor. Furthermore, tyrphostin inhibits zona-triggered acrosomal exocytosis in a dose-dependent manner. These findings indicate that the 95-kDa protein participates in a critical regulatory event of gamete interaction; moreover, our experiments suggest that sperm protein tyrosine kinase may be an excellent target for the control of fertility. | lld:pubmed |
