Source Description
UniProtTranscription factor involved in abiotic stress responses (PubMed:17293435, PubMed:19279197). May play a regulatory role in tolerance to salt, cold, and drought stresses (PubMed:17293435). Transcriptional activator that binds specifically to a mitosis-specific activator cis-element 5'-(T/C)C(T/C)AACGG(T/C)(T/C)A-3', found in promoters of cyclin genes such as CYCB1-1 and KNOLLE (AC Q84R43). Positively regulates a subset of G2/M phase-specific genes, including CYCB1-1, CYCB2-1, CYCB2-2, and CDC20.1 in response to cold treatment (PubMed:19279197). {ECO:0000269|PubMed:17293435, ECO:0000269|PubMed:19279197}.
UniProtTranscription factor that binds 5'-AACGG-3' motifs in gene promoters (By similarity). Transcription repressor that regulates organ growth. Binds to the promoters of G2/M-specific genes and to E2F target genes to prevent their expression in post-mitotic cells and to restrict the time window of their expression in proliferating cells (PubMed:26069325). {ECO:0000250|UniProtKB:Q94FL9, ECO:0000269|PubMed:26069325}.
