| 1353602 | FRMPD4 | FERM and PDZ domain containing 4 | This gene encodes a multi-domain (WW, PDZ, FERM) containing protein. Through its interaction with other proteins (such as PSD-95), it functions as a positive regulator of dendritic spine morphogenesis and density, and is required for the maintenance of excitatory synaptic transmission.

| 1617215 | Frmpd4 | FERM and PDZ domain containing 4 | Predicted to enable phosphatidylinositol-4,5-bisphosphate binding activity. Predicted to be involved in positive regulation of synapse structural plasticity and postsynaptic actin cytoskeleton organization. Is active in glutamatergic synapse and postsynaptic density. Is expressed in dorsal root gang lion; facial ganglion; lateral ventricle choroid plexus; metencephalon part of 4th ventricle choroid plexus; and trigeminal ganglion. Human ortholog(s) of this gene implicated in non-syndromic X-linked intellectual disability 104. Orthologous to human FRMPD4 (FERM and PDZ domain containing 4).
