Protein: Protein unc-80 homolog (Q8N2C7)
Organism: Homo sapiens (Human)
Function: 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).
Subcellular location: Cell membrane {ECO:0000269|PubMed:32494638}; Multi-pass membrane protein {ECO:0000255}.
