RGA

DELLA protein RGA

587 amino acids

Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. Probably acts by participating in large multiprotein complexes that repress transcription of GA-inducible genes. Positively regulates XERICO expression in seeds. Upon GA application, it is degraded by the proteasome, allowing the GA signaling pathway. Compared to other DELLA proteins, it is the most sensitive to GA application. No effect of the BOI proteins on its stability. Its activity is probably regulated by other phytohormones such as auxin and ethylene, attenuation of auxin transport delaying its GA-induced degradation.

Belongs to the GRAS family. DELLA subfamily.

Rga

Regulator of gene activity

585 amino acids

Component of the CCR4-NOT complex which is one of the major cellular mRNA deadenylases and is linked to various cellular processes including bulk mRNA degradation, miRNA-mediated repression, translational repression during translational initiation and general transcription regulation. Additional complex functions may be a consequence of its influence on mRNA expression. Essential for viability. Acts as a suppressor of position effect variegation (PEV) at the white locus and regulates the expression of several unrelated genes.

Belongs to the CNOT2/3/5 family.
