Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables calcium channel regulator activity. Involved in several processes, including neurotransmitter receptor localization to postsynaptic specialization membrane; postsynaptic density assembly; and presynaptic modulation of chemical synaptic transmission. Acts upstream of or within neurotransmitter secretion and synapse assembly. Part of protein-containing complex. Is active in GABA-ergic synapse and glutamatergic synapse. Is expressed in several structures, including inner ear; nervous system; neural retina; urinary system; and vibrissa. Orthologous to human NRXN3 (neurexin 3).
