NCBI Protein Information
Cyclic nucleotide-regulated ion channel family protein
NCBI Summary
'defense, no death' gene (DND1) encodes a mutated cyclic nucleotide-gated cation channel; Same as CNGC2 (article ID 229): Cyclic nucleotide gated channel, activated by cAMP, conducts K+ and other monovalent cations but excludes Na+, does not contain the GYG amino acid sequence found in other channels with this conductivity profile. Conducts Ca2+ into cells which is linked to the generation of NO and the NO signaling pathway involved in the innate immune response to pathogens.

UniProt Comments
Acts as cyclic nucleotide-gated ion channel. Permeable to potassium and calcium in a cyclic nucleotide-dependent fashion (cAMP or cGMP). Could also transport lithium, cesium and rubium and displays a strong selectivity against sodium. Seems to directly participate in pathogen-induced calcium influx. May function in homeostasis, re-establishing ionic balance after defense action and/or other stimuli. Could mediate the initiation of the developmentally regulated cell death programs.
