S is supported by the wide range of phenotypes described for hypomorphic and null mutants of CUL1. While complete loss of the cullin is embryo-lethal and causes abortion of embryogenesis at the early globular stage, hypomorphic mutants show pleiotropic defects related to lateral organ initiation, flower development, photomorphogenesis, and auxin and jasmonate signaling, as well as the circadian cl

Iversity is found in the F-box protein superfamily, which in A. thaliana consists of 694 predicted members, and up to 1350 predicted members in the closely related species A. lyrata (Gagne et al., 2002; Hua et al., 2011). Besides the F-box domain, these proteins frequently contain additional protein-protein interaction motifs such as LRR (leucine-rich), KELCH, or WD40 repeats, to facilitate bindin

Uch larger number of S-PHASE KINASEASSOCIATED PROTEIN 1 (SKP1)-like and F-box proteins exist. Arabidopsis encodes for 21 SKP1-like or ARABIDOPSIS SKIP (ASK)-like proteins (Risseeuw et al., 2003), which can be grouped into two major clades, with ASK1 (At1g10940) to 19 (At2g03160) representing one clade while ASK20 (At2g45950) and ASK21 (At3g61415) comprising the other.

Ullin-repeats. Each of these repeats are composed of a five-helix structural motif in which the helices C to E are organized as a three-helix bundle that interacts with helices A and B to form the cullin repeat (Zheng et al., 2002b). Specifically the first repeat is responsible for binding the substrate adaptor complex of SkpCullin-based Ubiquitin E3 Ligases3 ofand the F-box protein, while the oth
