Protein attributes

Sequence length	151 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Essential component of the SCF-type E3 ligase complex, SCF(GID2), a complex that positively regulates the gibberellin signaling pathway. Upon gibberellin treatment, the SCF(GID2) complex mediates the ubiquitination and subsequent degradation of DELLA proteins (GAI, RGA and RGL2), some repressors of the gibberellin pathway, leading to activate the pathway.
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Part of some SCF(GID2) complex, which consist of SKP1B, CUL1 cullin, GID2/SLY1 and some RING box protein. Interacts directly with SKP1A and SKP1B. Interacts directly with DELLA proteins GAI, RGA, RGL1, RGL3 and probably RGL2. May have a higher affinity for phosphorylated DELLA proteins.
Subcellular location	Nucleus.
Tissue specificity	Expressed in all tissues tested, including rosette leaves, green siliques, flowers, stems, cauline leaves and seedlings.
Sequence similarities	Contains 1 F-box domain.
