Science, 1995•science.orgMouse sperm recognize and bind to ZP3, one of three glycoproteins in the egg's zona
pellucida. A mouse sperm protein, sp56, was identified that has the characteristics expected
of the sperm protein responsible for recognition of ZP3. The complementary DNA encoding
sp56 was isolated, and its primary sequence indicates that sp56 is a member of a
superfamily of protein receptors. It was shown that sp56 expression is restricted to mouse
spermatids and that the presence or absence of sp56 on sperm from different species …

Mouse sperm recognize and bind to ZP3, one of three glycoproteins in the egg's zona pellucida. A mouse sperm protein, sp56, was identified that has the characteristics expected of the sperm protein responsible for recognition of ZP3. The complementary DNA encoding sp56 was isolated, and its primary sequence indicates that sp56 is a member of a superfamily of protein receptors. It was shown that sp56 expression is restricted to mouse spermatids and that the presence or absence of sp56 on sperm from different species accounts for species specificity of sperm-egg recognition in mice.
