Genes affected

TNP2 (HGNC:11952): (transition protein 2) Predicted to enable zinc ion binding activity. Predicted to be involved in positive regulation of protein processing; single fertilization; and spermatogenesis, exchange of chromosomal proteins. Predicted to act upstream of or within binding activity of sperm to zona pellucida and flagellated sperm motility. Predicted to be located in nucleus. Predicted to be part of nucleosome.
