Enables beta-catenin binding activity; nitric-oxide synthase binding activity; and protein kinase binding activity. Involved in several processes, including calcium-dependent cell-cell adhesion via plasma membrane cell adhesion molecules; regulation of glutamatergic synaptic transmission; and regulation of myelination. Located in several cellular components, including T-tubule; adherens junction; and fascia adherens. Is integral component of postsynaptic specialization membrane and integral component of presynaptic active zone membrane. Part of protein-containing complex. Is active in glutamatergic synapse. Human ortholog(s) of this gene implicated in agenesis of corpus callosum, cardiac, ocular, and genital syndrome; arrhythmogenic right ventricular cardiomyopathy; and arrhythmogenic right ventricular dysplasia 14. Orthologous to human CDH2 (cadherin 2). [provided by Alliance of Genome Resources, Apr 2022]
