Erratum: Actin in action: the interplay between the actin cytoskeleton and synaptic efficacy

Nature Reviews Neuroscience 9, 344–356 (2008) In Box 3 of the above article, the figure incorrectly showed CaMKK downstream of CaMKII. The figure should have shown two parallel pathways: one involving CaMKK–CaMKI signalling and another with CaMKII activating Rac1 via Kalirin-7 (see below). Correspondingly, the 5th sentence of the text in Box 3 should read: “Among the intracellular signalling events that are relevant for actin dynamics, of particular interest is the activation of the calmodulin-dependent kinase kinase (CaMKK)–CaMKI signalling pathway.
