Abstract

Hundreds of human cullin-RING E3 ligases (CRLs) modify thousands of proteins with ubiquitin (UB) to achieve vast regulation. Current dogma posits that CRLs first catalyze UB transfer from an E2 to their client substrates and subsequent polyubiquitylation from various linkage-specific E2s. We report an alternative E3-E3 tagging cascade: many cellular NEDD8-modified CRLs associate with a mechanistically distinct thioester-forming RBR-type E3, ARIH1, and rely on ARIH1 to directly add the first UB and, in some cases, multiple additional individual monoubiquitin modifications onto CRL client substrates. Our data define ARIH1 as a component of the human CRL system, demonstrate that ARIH1 can efficiently and specifically mediate monoubiquitylation of several CRL substrates, and establish principles for how two distinctive E3s can reciprocally control each other for simultaneous and joint regulation of substrate ubiquitylation. These studies have broad implications for CRL-dependent proteostasis and mechanisms of E3-mediated UB ligation.

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.
