| - | [ | + | [https://www.uniprot.org/uniprot/IZUM1_MOUSE IZUM1_MOUSE] Essential sperm cell-surface protein required for fertilization by acting as a ligand for IZUMO1R/JUNO receptor on egg. 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. The ligand-receptor interaction probably does not act as a membrane 'fusogen'.<ref>PMID:15759005</ref> <ref>PMID:24739963</ref> |
