Protein unc-80 homolog (UNC80)

Part of the NALCN sodium channel complex, required for channel regulation. This complex is a cation channel activated by neuropeptides substance P, neurotensin, and extracellular calcium that modulates neuronal excitability by controlling the dimensions of NALCN-dependent sodium-leak current.

UNC80 is vital for NALCN sensitivity to extracellular calcium. .
