RT "HLM1, an essential signaling component in the hypersensitive response, is
RT a member of the cyclic nucleotide-gated channel ion channel family.";
RL Plant Cell 15:365-379(2003).
CC -!- FUNCTION: Acts as cyclic nucleotide-gated ion channel. Permeable to
CC potassium and sodium in a cyclic nucleotide-dependent fashion (cAMP or
CC cGMP). Might constitute a common downstream component of the signaling
CC pathways leading to hypersensitive response (HR).
CC {ECO:0000269|PubMed:12566578}.
CC -!- SUBUNIT: Homotetramer or heterotetramer. {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q94AS9-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q94AS9-2; Sequence=VSP_008985, VSP_008986;
CC -!- INDUCTION: Induced by both ethylene and methyl jasmonate treatments, or
CC after pathogen attack.
CC -!- DOMAIN: The binding of calmodulin to the C-terminus might interfere
CC with cyclic nucleotide binding and thus channel activation.
CC {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: Loss-of-function mutation results in the loss of
CC the hypersensitive response leading to broad spectrum disease
CC resistance, and displays a lesion-mimic phenotype.
CC {ECO:0000269|PubMed:12566578}.
CC -!- SIMILARITY: Belongs to the cyclic nucleotide-gated cation channel (TC
CC 1.A.1.5) family. {ECO:0000305}.
