Differences in the kinetics of rod and cone synaptic transmission.

abstract：:Mitogen-activated protein kinases, MAP kinases or ERKs (extracellular signal-regulated kinases) are rapidly stimulated by growth-promoting factors acting on a variety of cell-surface receptors. In turn, ERKs phosphorylate and regulate key intracellular enzymes and transcription factors involved in the control of cellu...
