Function |
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'. {ECO:0000269|PubMed:15759005, ECO:0000269|PubMed:24739963}.
|
Subcellular Location |
Membrane {ECO:0000305}; Single-pass type I membrane protein {ECO:0000305}.
|
Tissue Specificity |
Sperm-specific (at protein level). Detectable on sperm surface only after the acrosome reaction. {ECO:0000269|PubMed:15759005, ECO:0000269|PubMed:19658160}.
