What is the function of this protein?
Voltage-gated ion channel responsible for the resting Na(+) permeability that controls neuronal excitability.  NALCN channel functions as a multi-protein complex, which consists at least of NALCN, NALF1, UNC79 and UNC80.  NALCN is the voltage-sensing, pore-forming subunit of the NALCN channel complex.  NALCN channel complex is constitutively active and conducts monovalent cations but is blocked by physiological concentrations of extracellular divalent cations (By similarity).  In addition to its role in regulating neuronal excitability, is required for normal respiratory rhythm, systemic osmoregulation by controlling the serum sodium concentration and in the regulation of the intestinal pace-making activity in the interstitial cells of Cajal.  NALCN channel is also activated by neuropeptides such as neurotensin and substance P (SP) through a SRC family kinases-dependent pathway.  In addition, NALCN activity is enhanced/modulated by several GPCRs, such as CHRM3 (By similarity).
