| Annotation description: | This paper describes how "knockdown of cortactin by short-interfering RNA (siRNA) results in a decrease of dendritic spines in hippocampal neurons, whereas overexpression of cortactin causes elongation of spines. In response to synaptic stimulation and NMDA receptor activation, cortactin redistributes rapidly from spines to dendritic shaft, correlating with remodeling of the actin cytoskeleton, implicating cortactin in the activity-dependent regulation of spine morphogenesis." Thus, cortactin seems implicated in spine morphology maintenance and activity-induced reorganization. Therefore, I chose the GO term "regulation of synapse organization" to combine these two functions. |
