Summary: Enables integrin binding activity. Involved in several processes, including fusion of sperm to egg plasma membrane involved in single fertilization; myoblast fusion involved in skeletal muscle regeneration; and paranodal junction assembly. Acts upstream of or within negative regulation of cell population proliferation. Located in external side of plasma membrane and extracellular exosome. Is expressed in several structures, including alimentary system; heart; nervous system; sensory organ; and urinary system. Human ortholog(s) of this gene implicated in prostate adenocarcinoma. Orthologous to human CD9 (CD9 molecule). [provided by Alliance of Genome Resources, Dec 2024]

CD9 and CD81 might coordinately prevent senescence and inflammation, partly by maintaining SIRT1 expression. Altogether, CD9/CD81 DKO mice represent a novel model for both COPD and accelerated senescence.
Title: Double deletion of tetraspanins CD9 and CD81 in mice leads to a syndrome resembling accelerated aging.
The spatiotemporal mapping of egg CD9 revealed that this protein concentrates at the egg/sperm interface as a result of sperm oscillations, until a CD9-rich platform is nucleated on which fusion immediately takes place. Within 2-5 min after fusion, most of the CD9 leaves the egg for the external aqueous medium.
Title: Egg CD9 protein tides correlated with sperm oscillations tune the gamete fusion ability in mammal.
The species-specific traits in CD9 and CD81 distribution during sperm maturation were compared between mice and humans. A mutual position of CD9/CD81 is shown in human spermatozoa in the acrosomal cap, however in mice, CD9 and CD81 occupy a distinct area.
Title: CD9 and CD81 Interactions and Their Structural Modelling in Sperm Prior to Fertilization.
The Cd9(-/-) and Cd9(-/-) Cd81(-/-) deletions are associated with a decreased microvilli density on the MII oocyte surface. Microvilli thickness is significantly increased whatever the deleted tetraspanin gene be. Only Cd9 deletion clearly disturbs the vesicular traffic, increasing the number of clathrin and exosome vesicles.

CD9 regulates the T cell-stimulatory capacity of granulocyte-macrophage colony-stimulating factor (GM-CSF)-dependent bone marrow-derived Dendritic Cells (BMDCs), without affecting antigen presentation by fms-like tyrosine kinase 3 ligand (Flt3L)-dependent BMDCs.

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.
