Zona-pellucida-binding (IPR010857)

Short name: Sp38-bd

Family relationships



This family contains a number of zona-pellucida-binding proteins that seem to be restricted to mammals. These are sperm proteins that bind to the 90 kDa family of zona pellucida glycoproteins in a calcium-dependent manner [PMID: 7729589]. These represent some of the specific molecules that mediate the first steps of gamete interaction, allowing fertilisation to occur [PMID: 9378618].
