Genes affected

ASTL (HGNC:31704): (astacin like metalloendopeptidase) Predicted to enable aspartic-type peptidase activity; glutamic-type peptidase activity; and metalloendopeptidase activity. Predicted to be involved in several processes, including negative regulation of binding activity of sperm to zona pellucida; positive regulation of protein processing; and prevention of polyspermy. Predicted to be located in cortical granule and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
