Source	Description
Uniprot	TISSUE SPECIFICITY: Widely expressed in the whole plant with high expression in leaves and stem. Broad expression within stomatal cell lineages of leaf epidermis. {ECO:0000269\|PubMed:18641265}.

Functional Description ? help Back to Top
Source	Description
UniProt	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). {ECO:0000269\|PubMed:17416732, ECO:0000269\|PubMed:18641265, ECO:0000269\|PubMed:28507175}.
