GENE INFORMATION
Gene name	CD9 (HGNC Symbol)
Synonyms	BA2, MIC3, MRP-1, P24, TSPAN29
Description	CD9 molecule (HGNC Symbol)
Entrez gene summary	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.
