Hence, phosphorylation of linker proteins not only bridges the TCR-associated PTK , ZAP-70 , with downstream effector proteins, but also provides a scaffold to integrate distinct signaling complexes to regulate T cell function .
 ( protein: ZAP-70, None) , ( protein: TCR-associated PTK, None) , ( protein: signaling complexes, None) , ( protein: linker proteins, None) , ( cell type: T cell, None)
