FUNCTION: Essential sperm cell-surface protein required for fertilization by acting as a ligand for IZUMO1R/JUNO receptor on egg (PubMed:15759005). 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). The ligand-receptor interaction probably does not act as a membrane 'fusogen' (PubMed:15759005). {ECO:0000269|PubMed:15759005}.
