Protein
SUPPRESSOR OF GAMMA RESPONSE 1
Organism
Arabidopsis thaliana
Function
Transcription factor regulating the transcriptional activation response to gamma irradiation (PubMed:19549833). Required for stem-cell death induced by UVB or by gamma irradiation (PubMed:20634150). Not required for ATM activation, but participates in pathways governed by both ATM and ATR sensor kinases (PubMed:19549833). Involved in DNA damage response (DDR) system that regulates cell cycle arrest (PubMed:24399300). Functional homolog of animal p53 (PubMed:24736489). Regulates SMR5 and SMR7 transcription (PubMed:24399300). Regulates DNA repair and cytokinin signaling separately and plays a key role in controlling lateral root formation under genotoxic stress.
