IZUMO1R ELISA kits are immunoassay tools for the measurement of the protein IZUMO1 receptor, JUNO, which is encoded by the IZUMO1R gene in humans. Functionally, this protein is a known receptor for IZUMO1 present at the cell surface of oocytes (oolemma), which is essential for species-specific gamete recognition and fertilization. The canonical protein structure is reported to have an amino acid length of 250 residues, a mass of 28.7 kDa, and is a member of the Folate receptor protein family. It is known to be localized in the cell membrane and is reported to be expressed in unfertilized oocytes. As many as 2 protein isoforms have been reported. The protein has been noted to be post-translationally glycosylated. Other alias names for this target include IZUMO1 receptor protein JUNO, IZUMO1 receptor, JUNO, FR-delta, folate receptor 4 (delta) homolog, folate receptor 4, delta (putative), and sperm-egg fusion protein Juno.
