Egg-lysin

UniProtKB accession:  P04552

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Creates a 3 um hole in the egg vitelline layer through which the sperm passes (PubMed:7106382). Does not have enzyme activity (PubMed:7106382). Species-specific interaction between the sperm protein lysin and the egg protein VERL exposes a basic surface on lysin that may dissociate the egg vitelline layer via electrostatic repulsion (PubMed:7106382, PubMed:28622512). Plays a role in ensuring species-specific fertilization (PubMed:2377618, PubMed:9192632, PubMed:28622512).
