UniProtKB description: Essential sperm cell-surface protein required for fertilization by acting as a ligand for IZUMO1R/JUNO receptor on egg (PubMed:15759005, PubMed:24739963, PubMed:27309808). The IZUMO1:IZUMO1R/JUNO interaction is a necessary adhesion event between sperm and egg that is required for fertilization but is not sufficient for cell fusion (PubMed:15759005, PubMed:24739963, PubMed:27309808). The ligand-receptor interaction probably does not act as a membrane 'fusogen' (PubMed:15759005, PubMed:24739963, PubMed:27309808). Plays a critical role in sperm-oolemma binding prior to plasma membrane fusion (PubMed:35096839). Can mediate cell-cell fusion in cultured mammalian cells independently of its binding to IZUMO1R/JUNO (PubMed:36394541).
