Predicted to enable several functions, including G protein-coupled glutamate receptor binding activity; identical protein binding activity; and protein C-terminus binding activity. Predicted to be involved in several processes, including G protein-coupled glutamate receptor signaling pathway; negative regulation of interleukin-2 production; and regulation of signal transduction. Predicted to be located in basal part of cell; cytosol; and glutamatergic synapse. Predicted to be active in several cellular components, including dendrite; plasma membrane; and postsynaptic density. Orthologous to human HOMER3 (homer scaffold protein 3).
