This gene encodes a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Tetraspanins are cell surface glycoproteins with four transmembrane domains that form multimeric complexes with other cell surface proteins. The encoded protein functions in many cellular processes including differentiation, adhesion, and signal transduction, and expression of this gene plays a critical role in the suppression of cancer cell motility and metastasis.

A study in humans demonstrated that exosomes and the CD9 are well-preserved in post-mortem body fluids, with no significant difference in the CD9 expression between exosomes from healthy donors and dead bodies, and its expression was sustained over 48 hours under simulated post-mortem conditions [Kim et al. DOI:10.3390/diagnostics12092153]. Another study in humans found that the CD9 expression was significantly lower in menstrual blood-derived mesenchymal stem cells from endometriosis patients compared to those from healthy women [Sahraei et al. DOI:10.1155/2022/7053521].
