Protein: Protein unc-79 homolog (Q9P2D8)
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. Activated by neuropeptides substance P, neurotensin, and extracellular calcium that regulates neuronal excitability by controlling the sizes of NALCN-dependent sodium-leak current.
Subcellular location: Cell membrane {ECO:0000269|PubMed:32494638}; Multi-pass membrane protein {ECO:0000255}.
Interaction partners:
- Protein unc-80 homolog
- Sodium leak channel NALCN
