Involved in ubiquitination and subsequent proteasomal degradation of target proteins. Part of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex (PubMed:28494021). Is able to form the SCF complex together with SKP1 and the rice black streaked dwarf virus RBSDV protein P7-2 (PubMed:28494021). Interacts with D3 (PubMed:24616269). Expressed in dry seeds and coleoptiles. Induced by abscisic acid, heat shock, salt stress and drought stress. Neddylated (rubylated) (PubMed:27137867). Deneddylation occurs upon interaction with the COP9 signalosome (CSN) complex (PubMed:27137867). Belongs to the cullin family.
