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. |
