Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway (PubMed:17521606). Its repressive activity is weaker than that of SLR1 (PubMed:17521606). Its overexpression prevents the GA signaling pathway and induces a dwarf phenotype in Arabidopsis thaliana plants (PubMed:17521606). Expressed at low levels in leaf blades, leaf sheaths, rachis and flowers (PubMed:16262715). Expressed in the embryo of immature seeds (PubMed:17521606). Induced by treatment with gibberellin (GA3). Belongs to the GRAS family.
