Phosphorylation of serine, threonine and tyrosine residues in substrate proteins by protein kinases (PKs) provides a fundamental mechanism for the control of cell division, growth and apoptosis, metabolic activity, adhesion and migration, and mediates cell responses upon environmental stimuli [1], [2], [3].
Also, as PHI genes (PHI-base accession: PHI 404 and PHI 441), they mediate cell response to inductive cues [ 45].
Growth factors, cytokines and other regulatory elements use these interactions to mediate cell responses, including proliferation, migration, angiogenesis, immune responses and cell death.
Furthermore, our data show that FcγR triggering influences Toll-like receptor (LPS) mediated cell responses.
GECs use PARs to recognize P. gingivalis and mediate cell responses involved in innate immunity.
At the M-band, the kinase domain of titin is a major player mediating cell responses to mechanical stress.
Given the characterized role of calcium channel in mediating cell responses to osmotic changes, it is worth further investigation whether VSOR elicits ER stress via cell volume regulation and subsequently disruption of Ca2+ homeostasis.
Thus, HER1, and specifically phosphorylation of Tyr 845 by c-Src, appears to play an important, perhaps widespread role in mediating cell responses to an array of external signals.
For instance, WRKY9 is involved in mediating cell responses to nutrient deprivation (Shin and Schachtman, 2004; Shin et al., 2005), and the transcription factor MYB46 has a prominent role in the developmental programme of secondary wall biosynthesis (Zhong et al., 2007, 2013).
The binding of these ligands to CCR4 helps to guide Tregs towards DC, mediates contact between these two cell types and thus inhibits activation of DC and the DC-mediated T cell response.
