Receptor for IZUMO1 present at the cell surface of oocytes, which is essential for species-specific gamete recognition and fertilization. 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'.
