ERK1/2 is regulated by a feedback mechanism targeting ERK1/2 itself or its ... WebPathway Description. Legend. T Cell Receptor (TCR) activation promotes a number of signaling cascades that ultimately determine cell fate through regulating cytokine production, cell survival, proliferation, and differentiation. An early event in TCR activation is phosphorylation of immunoreceptor tyrosine-based activation motifs (ITAMs) on the ...
