Dimerization of Substrate Adaptors Can Facilitate Cullin-mediated Ubiquitylation of Proteins by a “Tethering” Mechanism
Open accessAbstract
The prevalence and mechanistic significance of self-association among substrate adaptors for the Cul-Rbx family of ubiquitin ligases remain unclear. We now report that it is as a homodimer that the substrate adaptor Keap1 interacts with Cul3. The resulting complex facilitates ubiquitylation of the Nrf2 transcription factor but only when this substrate possesses within its Neh2 domain a second cryptic Keap1-binding site, the DLG motif, in addition to its previously described ETGE site. Both motifs recognize overlapping surfaces on Keap1, and the seven lysine residues of Nrf2 that act as ubiquitin acceptors lie between them. Based on these data, we propose a "fixed-ends" model for Nrf2 ubiquitylation in which each binding site becomes tethered to a separate subunit of the Keap1 homodimer. This two-site interaction between Keap1 and Nrf2 constrains the mobility of the target lysine residues in the Neh2 domain, increasing their average concentration in the vicinity of the Rbx-bound ubiquitin-conjugating enzyme, and thus the rate at which the transcription factor is ubiquitylated. We show that self-association is a general feature of Cul3 substrate adaptors and propose that the fixed-ends mechanism is commonly utilized to recruit, orientate, and ubiquitylate substrates upon this family of ubiquitin ligases.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
