Lrrtm2 - leucine rich repeat transmembrane neuronal 2

Enables neurexin family protein binding activity. Involved in regulation of postsynaptic density assembly. Acts upstream of or within synapse organization. Located in excitatory synapse. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and hippocampal mossy fiber to CA3 synapse. Is integral component of postsynaptic density membrane. Orthologous to human LRRTM2 (leucine rich repeat transmembrane neuronal 2). [provided by Alliance of Genome Resources, Apr 2022]
