| Post Translational Modification | Palmitoylated at a low; basal level in unstimulated platelets. The level of palmitoylation increases when platelets are activated by thrombin (in vitro). The protein exists in three forms with molecular masses between 22 and 27 kDa; and is known to carry covalently linked fatty acids (PubMed-11959120). Palmitoylation by ZDHHC2 regulates CD9 expression; association with other tetraspanin family proteins and function in cell adhesion (PubMed-18508921). |
| Function | Integral membrane protein associated with integrins; which regulates different processes; such as sperm-egg fusion; platelet activation and aggregation; and cell adhesion |
