The nuclear envelope is a membrane system which surrounds the nucleoplasm of eukaryotic cells. It is composed of the nuclear lamina, nuclear pore complexes and two nuclear membranes. The space between the two membranes is called the nuclear intermembrane space.
The membrane surrounding the nucleus. This term is used when it is not known if the protein is found in or associated with the inner or outer nuclear membrane.
Ion channel with a moderate preference for potassium over sodium and calcium. Involved in perinuclear calcium spiking but not in cytosolic calcium influx. Closed at negative voltages in presence of magnesium. Required for early signal transduction events leading to endosymbiosis. Acts early in a signal transduction chain leading from the perception of Nod factor to the activation of calcium spiking. Also involved in fungal entry into root epidermal cells during the establishment of the arbuscular mycorrhizal symbiosis. {Experimental EvidencePubMed:16903357, Experimental EvidencePubMed:19106374}.
