Leucine-rich repeat-containing protein 4 is a protein that in humans is encoded by the LRRC4 gene.

This gene is significantly downregulated in primary brain tumors. The exact function of the protein encoded by this gene is unknown. [provided by RefSeq, Jul 2008].

Function: Synaptic adhesion protein. Regulates the formation of exitatory synapses through the recruitement of pre-and-postsynaptic proteins. Organize the lamina/pathway-specific differentiation of dendrites. Plays a important role for auditory synaptic responses. Involved in the suppression of glioma (By similarity).
