  • FUNCTION 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. Upon GA application, it is degraded by the proteasome, allowing the GA signaling pathway. In contrast, its overexpression prevents the GA signaling pathway and induces a dwarf phenotype.SUBUNIT May be a homodimer. Interacts directly with the GID2 component of the SCF(GID2) complex. Interacts with GID1 in a GA-dependent manner, probably leading to its interaction with GID2 and its subsequent degradation (PubMed:12649483, PubMed:14756772, PubMed:16193045). Interacts with D14 and GID1 in an strigolactone-dependent manner (PubMed:24131983). Interacts with HD16/EL1 (PubMed:20400938, PubMed:23789941).INTERACTION Expressed in nodes, internodes, leaf sheats of young seedlings and ears of adult plants. Weakly expressed in leaf blade and root.DEVELOPMENTAL STAGE At the vegetative stage, it is expressed in rapidly elongating and dividing organs and tissues. At the influorescence or floral stage, it is expressed in the shoot meristems and stamen primordia.INDUCTION Up-regulated following GA3 but not ABA application.DOMAIN The DELLA motif is required for its GA-induced degradation.PTM Phosphorylated on Ser/Thr residues in the N-terminal part. Both phosphorylated and unphosphorylated forms are degraded upon GA treatment, suggesting that phosphorylation does not trigger ubiquitination (PubMed:12649483, PubMed:14756772, PubMed:15979983). Phosphorylated by HD16/EL1. Phosphorylation enhances its stability (PubMed:20400938, PubMed:23789941).PTM Ubiquitinated. Upon GA application it is ubiquitinated by the SCF(GID2) complex, leading to its subsequent degradation.SIMILARITY Belongs to the GRAS family. DELLA subfamily.
