Summary: Enables protein homodimerization activity. Predicted to be involved in fusion of sperm to egg plasma membrane involved in single fertilization; heterotypic cell-cell adhesion; and sperm-egg recognition. Predicted to be located in acrosomal vesicle and endoplasmic reticulum membrane. Predicted to be part of protein complex involved in cell-cell adhesion. Predicted to be active in acrosomal membrane and plasma membrane. Orthologous to human IZUMO1 (izumo sperm-oocyte fusion 1). [provided by Alliance of Genome Resources, Dec 2024]

Participation of WD repeat-containing protein 54 (WDR54) in rat sperm-oocyte fusion through interaction with both IZUMO1 and JUNO.

four phosphopeptide changes came from Izumo1, the sperm-egg fusion protein, in the cytoplasmic segment of the protein. 2D-PAGE confirmed that Izumo1 is post-translationally modified during epididymal transit.
Title: Analysis of phosphopeptide changes as spermatozoa acquire functional competence in the epididymis demonstrates changes in the post-translational modification of Izumo1.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
