Molecular morphogens for dendritic spines.
Three protein components of the postsynaptic density--Shank, Homer and SPAR--have been found to regulate the structural and molecular organization of dendritic spines. These new studies reveal linkages between receptor complexes, the actin cytoskeleton and signaling molecules that help shape spines.
