Entrez Gene Summary for IZUMO1 Gene

  • The sperm-specific protein Izumo, named for a Japanese shrine dedicated to marriage, is essential for sperm-egg plasma membrane binding and fusion (Inoue et al., 2005 [PubMed 15759005]).[supplied by OMIM, Mar 2008]

GeneCards Summary for IZUMO1 Gene

IZUMO1 (Izumo Sperm-Egg Fusion 1) is a Protein Coding gene. Diseases associated with IZUMO1 include Hajdu-Cheney Syndrome and Glaucoma, Primary Open Angle. Among its related pathways are Reproduction. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and receptor binding.

UniProtKB/Swiss-Prot for IZUMO1 Gene

  • 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.
