Data are representative of two independent experiments. b, SDS-PAGE analysis of ARISC(E33A)–RAP80, ARISC(E33A) BRCC36(S98K) –RAP80, ARISC(E33A) Abraxas1(Δ42-55) –RAP80, and ARISC(E33A) BRCC45(ΔLoop) –RAP80. dStrepII, double StrepII tag. * indicates Abraxas1 degradation product. c, Spectral shift assays measuring binding of labelled ARISC(E33A)–RAP80 or the indicated mutant complexes (40 nM) to cyclical K63-Ub6 chains (20 µM-0 µM). Data points are mean ± SEM of two independent experiments carried out in technical duplicates. Dissociation constants (K d ) are indicated; CI, confidence interval. d, Representative images of WT or mutants BRCC36 IRIF in HT-29 cells 4 h post irradiation (10 Gy). Scale bar is 10 µm. e, Western blots showing BRCC36 protein levels in HT-29 cells reconstituted with WT or mutants BRCC36 as indicated (l eft ). Scatter plot showing quantification of the BRCC36 IRIF described in d . Data represent mean ± SEM derived from n ≥ 300 nuclei examined over two independent experiments; p values are indicated, unpaired two-tailed t test ( right ). f, K63-Ub2, -Ub4, and -Ub7 chains (1 µM) were incubated with ARISC WT or ARISC Δ42-55 (Abraxas1 Δ42-55) (5 nM) for up to 60 minutes. Cleavage activity was analysed as in a . Data are representative of two independent experiments. DUB, deubiquitylating enzyme; WT, wild type; Ub, ubiquitin.
