Essential component of some SCF-type E3 ligase complex that positively regulates the gibberellin signaling pathway. Upon gibberellin treatment, the complex mediates the ubiquitination and subsequent degradation of DELLA protein SLR1, a repressor of the gibberellin pathway, leading to activate the pathway. Protein modification; protein ubiquitination. Part of some SCF(GID2) complex, which consist of a SKP1 protein, CUL1, GID2 and some RING box protein. Interacts directly with SKP2 and SKP15. Interacts directly with DELLA protein SLR1. May have a higher affinity for phosphorylated SLR1 proteins. Widely expressed. Preferentially expressed in unopened flowers, shoot apices and elongation stem. Expressed at lower level in the leaf blades, leaf sheaths, roots and rachis.
