Synaptic adhesion protein. Regulates the formation of exitatory synapses through the recruitment of pre-and-postsynaptic proteins. Organize the lamina/pathway-specific differentiation of dendrites. Plays an important role for auditory synaptic responses. Involved in the suppression of glioma (By similarity).
Subcellular locations: Membrane, Postsynaptic cell membrane
LRRC4 and DLG4 are interdependent for synaptic localization.
Specifically expressed in brain.
