Activation of calcium/calmodulin-dependent kinase kinases, CaMKKs (CAMKK1 and CAMKK2), upon calcium influx through activated NMDA receptors, leads to activation of the cytosolic calcium/calmodulin kinase CaMKI (CAMK1). One of the CAMK1 targets is the RAC1 guanine nucleotide exchange factor ARHGEF7 (beta-Pix). Activation of RAC1 is involved in NMDA-receptor triggered synaptogenesis (Saneyoshi et al. 2008).
