Tetraspanins-structural and signaling scaffolds that regulate platelet function

There are several tetraspanins present in platelets including CD9, CD151, TSSC6, and CD63. Recent studies in knockout mouse models have revealed that CD151 and TSSC6 are physically and functionally involved in regulation of the 'outside-in' signalling properties of the major platelet integrin, integrin aiib B3 and thrombus stability in vivo.
