Gene : ICE1 A. thaliana

DB identifier  ? AT3G26744 Secondary Identifier  ? locus:2090847
Name  ? INDUCER OF CBF EXPRESSION 1 Brief Description  basic helix-loop-helix (bHLH) DNA-binding superfamily protein
TAIR Computational Description  basic helix-loop-helix (bHLH) DNA-binding superfamily protein;(source:Araport11)
TAIR Curator Summary  Encodes a MYC-like bHLH transcriptional activator that binds specifically to the MYC recognition sequences in the CBF3 promoter. It also binds to and inhibits the expression of ABI3. Mutants are defective in cold-regulated gene expression and ABA signaling druing seed germination.. Cold stress triggers protein degradation of nuclear GFPICE1 protein, and the RING finger protein HOS1 is required. Sumoylation of ICE1 controls CBF3/DREB1A expression and freezing tolerance. Together with ZOU, ICE1 determines primary seed dormancy depth independently of their joint role in endosperm development.ICE1 interacts with ABI5. Also members of the DELLA family, which repress ICE1 function.

ICE1_ARATH-2 ICE1_ARATH function Transcriptional activator that regulates the cold-induced transcription of CBF/DREB1 genes. Binds specifically to the MYC recognition sites (5'-CANNTG-3') found in the CBF3/DREB1A promoter. Mediates stomatal differentiation in the epidermis probably by controlling successive roles of SPCH, MUTE, and FAMA. Functions as a dimer with SPCH during stomatal initiation (PubMed:18641265, PubMed:28507175).
ICE1_ARATH-2 ICE1_ARATH tissue specificity Widely expressed in the whole plant with high expression in leaves and stem. Broad expression within stomatal cell lineages of leaf epidermis.
