Two egg-derived molecules in sperm motility initiation and fertilization in the Pacific herring (Clupea pallasi)

1 Jan 2008

Abstract excerpt

Sperm of the Pacific herring are immotile at spawning. Two egg-derived molecules are capable of initiating sperm motility. One is herring sperm activating protein(s) (HSAPs) and the other is sperm motility initiation factor (SMIF). These two motility initiators differ in their location and association with the chorion, and in their isoelectric points and molecular weights. In this study we have investigated the...
