Protein
Transcription repressor OFP1
Organism
Arabidopsis thaliana
Function
Transcriptional repressor that regulates multiple aspects of plant growth and development through the regulation of BEL1-LIKE (BLH) and KNOX TALE (KNAT) homeodomain transcription factors. Controls the subcellular localization of the homeodomain protein BLH1. Plays a role in the regulation of cell elongation by controlling the expression of GA20OX1, a gene that encodes a key enzyme in gibberellin biosynthesis. May play a role in double-stranded DNA repair through the DNA non-homologous end joining (NHEJ) pathway along with KU70 and KU80 protein complex. Possesses DNA-binding activity towards double-stranded and single-stranded DNA in vitro.
