Homer proteins are closely related neuronal scaffolding molecules that selectively binds the C-terminus of group 1 metabotropic or heterotrimeric GTP-binding protein-linked glutamate receptors (mGluR1a and mGluR5) and are enriched at excitatory synapses (Brakeman et al. 1997, Xiao et al. 1998). Homer proteins contain an amino-terminal EVH1 domain followed by a rod-shaped coiled-coil domain. The EVH1 domain of Homer can bind the proline rich motifs in mGluRs and the inositol 1,4,5-trisphosphate (IP3) receptors, thereby linking these receptors in a signalling complex (Tu et al. 1998, 1999).
