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. The DELLA motif is required for its GA-induced degradation. Phosphorylated. Ubiquitinated. Upon GA application it is ubiquitinated, leading to its subsequent degradation (By similarity). In cv. Pinot Meunier, 1 of the 3 cultivars used for the sparkling wine Champagne, plants are genetically indistinguishable from Pinot noir in most cells, but their outer layer, the 'L1' epidermal cell layer, is different: cv. Pinot Meunier has a furry surface on its leaves whereas Pinot noir does not. This is due to the Ser-387 variant that is present only in cells of the L1 layer that causes this difference, demonstrating that GA inhibits flowering in grapewine. Belongs to the GRAS family.
