doi: 10.7554/eLife.85837

Figure Lengend Snippet: ( A ) USP19 induced α-syn secretion in the medium, which was further enhanced by WT DNAJC5 and blocked by two DNAJC5 palmitoylation-deficient mutants (L115R and L116Δ). ( B ) Both mutations, L115R and L115Δ, inhibited DNAJC5 palmitoylation in HEK293T cells. ( C ) Quantification of normalized α-syn secretion in HEK293T cell transfected with indicated constructs. The quantification was based on immunoblot in ( A ) and ( B ). α-Syn secretion was calculated as the amount of α-syn in media divided by the amount in lysate.

Article Title: USP19 deubiquitinates EWS-FLI1 to regulate Ewing sarcoma growth

doi: 10.1038/s41598-018-37264-5

Figure Lengend Snippet: SiRNA screen identifies USP19 as a modulator of EWS-FLI1 stability. ( a ) In-silico selection of candidates. 21 deubiquitinating enzymes were selected based on their expression levels from publicly available microarray data sets of Ewing cell lines and tumors. ( b ) Screening setup. A673 and RDES cells stably expressing flag-tagged EWS-FLI1 were reverse transfected with single siRNAs from a small siRNA library. After 48 h, lysates were incubated in anti-flag coated plates to determine EWS-FLI1 protein normalized to total protein input. ( c ) EWS-FLI1 protein levels upon candidate knockdown. Each dot represents 3xflag-EWS-FLI1 protein levels normalized to its total protein for each single well. 3xflag-EWS-FLI1 levels upon USP19 knockdown are indicated with larger red dots and upon EWS-FLI1 knockdown in orange. ( d ) Expression levels of USP19 in indicated cell lines and primary samples were analyzed by western blot using USP19 antibody. The arrows indicate specific USP19 isoforms, asterisk marks unspecific band. ( e ) mRNA expression of USP19 was determined by quantitative RT-PCR from same cells and normalized to GAPDH.

doi: 10.1038/s41598-018-37264-5

Figure Lengend Snippet: EWS-FLI1 ubiquitination is modulated by USP19. ( a ) EWS-FLI1 interacts with USP19. 3xflag-EWS-FLI1 and 3xmyc-USP19 were co-expressed in HEK293T cells for 48 h. After co-immunoprecipitation, lysates were analyzed by western blotting as indicated. ( b ) USP19 depletion increases EWS-FLI1 ubiquitination. A673 cells were transiently incubated with three different siRNAs against USP19 or a control siRNA for 24 h followed by co-expression of 3xflag-EWS-FLI1 and HA-ubiquitin for 48 h. Ubiquitination of EWS-FLI1 was analyzed by western blot analysis using anti-HA antibody. ( c ) EWSR1 also immunoprecipitates with USP19. 3xflag-EWS-FLI1, 3xflag-EWSR1 or 3xflag-FLI1 were co-expressed with 3xmyc-USP19 in HEK293 cells for 48 h. After co-immunoprecipitation, lysates were analyzed by western blotting as indicated. ( d ) USP19 depletion increases EWSR1 monoubiquitination. A673 cells were transiently incubated with two different siRNAs against USP19 or a control siRNA for 24 h followed by co-expression of 3xflag-EWSR1 and HA-ubiquitin for 48 h. Ubiquitination of EWSR1 was analyzed by western blot analysis using anti-HA antibody. Full-length blots of all immunoprecipitates are presented in Supplementary Fig. .

Figure Lengend Snippet: USP19 selectively stabilizes EWS-FLI1. ( a ) USP19 binds to the EWS-FLI1 fusion protein which is further deubiquitinated. ( b ) USP19 also binds to the stable EWSR1 full length protein resulting in removal of the monoubiquitin. As USP19 does not bind to full length FLI1, its polyubiquitination pattern is unaffected.
