Transcription factor E2FA

Gene

E2FA

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Transcription activator that binds DNA cooperatively with DP proteins through the E2 recognition site, 5'-TTTC[CG]CGC-3' found in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication. The binding of retinoblastoma-related proteins represses transactivation. Regulates gene expression both positively and negatively. Activates the expression of E2FB. Involved in the control of cell-cycle progression from G1 to S phase. Stimulates cell proliferation and delays differentiation.9 Publications
