CD9 is a gene encoding a protein that is a member of the transmembrane 4 superfamily also known as the tetraspanin family. It is a cell surface glycoprotein that consists of four transmembrane regions and has two extracellular loops that contain disulfide bonds which are conserved throughout the tetraspanin family.[5][6][7] Also containing distinct palmitoylation sites that allows CD9 to interact with lipids and other proteins.[5][8][9]
