Lck-dependent Fyn activation requires C terminus-dependent targeting of kinase-active Lck to lipid rafts

Mechanisms regulating the activation and delivery of function of Lck and Fyn are central to
the generation of the most proximal signaling events emanating from the T cell antigen
receptor (TcR) complex. Recent results demonstrate that lipid rafts (LR) segregate Lck and
Fyn and play a fundamental role in the temporal and spatial coordination of their activation.
Specifically, TcR-CD4 co-aggregation-induced Lck activation outside LR results in Lck
translocation to LR where the activation of LR-resident Fyn ensues. Here we report a …
