CC -!- FUNCTION: Synaptic adhesion protein. Regulates the formation of
CC exitatory synapses through the recruitment of pre-and-postsynaptic
CC proteins. Organize the lamina/pathway-specific differentiation of
CC dendrites. Plays an important role for auditory synaptic responses.
CC Involved in the suppression of glioma. {ECO:0000269|PubMed:15967442,
CC ECO:0000269|PubMed:16980967, ECO:0000269|PubMed:17785411}.
CC -!- SUBUNIT: Interacts (via LRR repeats) with NTNG2. Interacts with DLG4.
CC Forms a complex with DLG4 and with NMDA receptors.
CC {ECO:0000269|PubMed:16980967, ECO:0000269|PubMed:17973922}.
CC -!- SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
CC Postsynaptic cell membrane {ECO:0000250}. Note=LRRC4 and DLG4 are
CC interdependent for synaptic localization. {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Specifically expressed in brain. In the
CC hippocampus, parietal cortex and piriform cortex expressed in proximal
CC segments of CA1 pyramidal neurons. {ECO:0000269|PubMed:15967442,
CC ECO:0000269|PubMed:17785411}.
CC -!- DOMAIN: The last 4 C-terminal residues bind to the first 2 PDZ domains
CC of DLG4.
CC -!- PTM: N-glycosylated. {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: Mutant mice dysplay impaired startle response to
CC acoustic stimulus. {ECO:0000269|PubMed:17973922}.
