DESCRIPTION

Also known as UNC80_HUMAN, UNC80, C2orf21, KIAA1843. Auxiliary subunit of the NALCN sodium channel complex, a voltage-gated ion channel responsible for the resting Na(+) permeability that controls neuronal excitability (By similarity). Activated by neuropeptides substance P, neurotensin, and extracellular Ca(2+) that regulates neuronal excitability by controlling the sizes of NALCN-dependent sodium-leak current. UNC80 is essential for NALCN sensitivity to extracellular Ca(2+) (By similarity). NALCN complex consists of NALCN and auxiliary subunits, UNC79, UNC80 and NACL1. These auxiliary subunits are essential for the NALCN complex function (By similarity). Interacts (via N-terminus half) with NALCN; this interaction facilitates NALCN surface localization (By similarity). Interacts with UNC79 (By similarity). UNC80 bridges NALCN to UNC79 (By similarity).
