Protein
Inward rectifier potassium channel irk-1
Organism
Caenorhabditis elegans
Function
Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Required for modulation of the activity of the hermaphrodite-specific neurons (HSNs) by the G-protein coupled neuropeptide receptor egl-6 which in turn controls egg-laying behavior.
Similarity
Belongs to the inward rectifier-type potassium channel (TC 1.A.2.1) family.
