"Study characterized the functional roles of the two brain-specific phosphorylation sites (S582 and T1067) of CYFIP2 in cultured hippocampal neurons; found that overexpression of the phospho-blocking T1067A mutant significantly decreased the density of stubby spines but not other types of spines. Study found that T1067 phosphorylation of CYFIP2 could potentially weaken the interaction between CYFIP2 and Nap1."xsd:string
