The cAMP-responsive element binding protein (CREB), a key regulator of gene expression, is activated by phosphorylation on Ser-133. Several different protein kinases possess the capability of driving this phosphorylation, making it a point of convergence for multiple intracellular signaling cascades. Work in neurons has indicated that physiologic synaptic stimulation recruits a fast calmodulin kinase IV (CaMKIV)-dependent pathway that dominates early signaling to CREB. Activated CaMKIV (CAMK4) phosphorylates CREB1 at S133, thereby initiating the transcription of CREB1-regulated set of genes, leading to protein synthesis and long lasting changes that underlie synaptic plasticity.
