RNF26 is an E3 ubiquitin ligase for MITA.Figure 1(A) Overexpression of RNF26 promoted polyubiquitination of MITA. The 293 cells (5×106) were transfected with Flag-MITA (5 µg) and HA-Ub (1 µg) together with a control or RNF26 expression plasmid (0.5, 1, 2 µg). Twenty-four hours after transfection, cells were subjected to immunoprecipitation (IP) under denatured conditions with anti-Flag and the immunoprecipitates were analyzed by immunoblots with anti-HA (upper panel) or anti-Flag (lower panel). The whole cell lysates were analyzed by immunoblots with anti-HA (upper panel), anti-Flag (middle panel) and anti-RNF26 (bottom panel). Ub, ubiquitin. (B) RNF26-mediated polyubiquitination of MITA depends on the enzymatic activity of RNF26. The 293 cells (5×106) were transfected with Flag-MITA (5 µg) and HA-Ub (1 µg) together with RNF26 or its mutants (1 µg each).

The LRR RLK PRK5 is required for GRI‐peptide‐induced ion leakageInfiltration of GRIp65–84 induced cell death similar to GRIp31–96.Figure 1A Infiltration of GRIp65-84 induced cell death similar to GRIp31-96. Bacterially produced 37 nM GST, GST‐GRIp31-96 or biochemically pure GRI‐peptides (GRIp31-96, GRIp31-51, GRIp47-68, GRIp65-84, GRIp80-96) were infiltrated into leaves of Col‐0 plants. B Infiltration of increasing concentrations of GRIp65-84 into Col‐0leaves, electrolyte leakage was measured after 12 h. Background (red line) shows ion leakage from infiltration of leaves with increasing concentrations of (inactive) GRIp80-96. C Infiltration of leaves with 37 nM GRIp31-96 induced elevated ion leakage in Col‐0 and prk4, but not in prk5‐1 or prk5‐2. Infiltration with GST caused the same background effect for all lines. D Genomic complementation of prk5 rescues the insensitivity to induction of elevated ion leakage by GRIp31-96. E Enzymatic superoxide production from xanthine/xanthine oxidase (XXO) induced more electrolyte leakage in gri compared to Col‐0 or prk5‐1, prk5‐2 and prk4 after infiltration into leaves. Infiltration with xanthine buffer (X) was used as a control.

Figure 2Portion of the 1H-15N TROSY NMR spectrum showing signals from R0RBR parkin within the R0RBR:pUb complex (black) and in the presence of one equivalent of the unlabelled UbcH7-Ub conjugate (blue). Signals that shift in the presence of UbcH7-Ub are indicated by arrows. Some signals shift and broaden and cannot be identified in the bound state. Boxes indicate signals that have shifted and are visible at very low contour level. Two distinct surfaces are revealed on parkin upon binding of the UbcH7-Ub conjugate. Chemical shift perturbations were measured from 1H-15N TROSY spectra of 2H,13C,15N-labelled R0RBR parkin bound to unlabelled pUb in the absence and presence of one equivalent unlabelled UbcH7-Ub. Chemical shift perturbations (absence of signal, average shift + 1 SD) are modelled onto the surface of R0RBR bound to pUb (PDB 5N2W). The UbcH7-Ub binding site comprises the RING1 and IBR regions (magenta). An adjacent site composed of many buried residues was also observed (cyan) that results from E2-Ub binding but does not include the E2 binding site. Sections of the tether and linker regions not visible in the crystal structure were added using Modeller (Eswar et al, 2006) so that chemical shift changes for residues not observed in crystal structures could be mapped. Model of R0RBR:pUb in complex with UbcH7-Ub derived from NMR chemical shift data and HADDOCK docking (Dominguez et al, 2003). The lowest energy structure is shown and the top 20 structures all showed excellent agreement (RMSD 0.71 ± 0.1Å) although some minor differences were noted for the orientation of the Ub molecule. The structure shows that UbcH7-Ub binds in an open conformation. UbcH7 uses canonical E2-RING E3 interactions that include residues from two loops in the RING1 domain (L1, L2) and two loops in the E2 enzyme (L4, L7) to stabilize the interaction. Ub binds to a RING1/IBR pocket. In this model no attempt was made to move or re-orient any of the domains in parkin Effects of ubiquitin surface mutants based on the UbcH7-Ub:R0RBR:pUb model for the ubiquitin loading and off-loading potential of pParkinCH (pParkinC431S,H433A). Coomassie stained gels (top) depict the formation of a pParkinCH ~ Ub oxyester intermediate after 60 minutes in the absence and presence of pUb using the indicated ubiquitin species. Anti-HA blots (bottom) depict the ubiquitination of HA-tagged Miro1181-579 by pParkin after 10 minutes in the absence and presence of pUb using the indicated ubiquitin species. The E24A substitution in Ub is a negative control as this residue faces away from the interface with parkin. Auto-ubiquitination assay for parkin using ARJP and non-ARJP substitutions in parkin observed near the interface with UbcH7-Ub. Assays were done in the absence and presence of pUb. Experiments with PINK1 were done by treating parkin:pUb with PINK1 for 30 minutes prior to adding other reagents needed for ubiquitination. Assays were monitored using a DyLight-labelled Ub protein and measuring fluorescence at 800 nm.
RUSH assay to analyze trafficking of SBP-GFP-GluK2 in HEK293T cells.Figure 6A) Schematic representation of the RUSH Cargo Sorting Assay using Confocal Microscopy. HEK293T cells were transfected with the SBP-GFP-GluK2 plasmid, that expresses a fusion protein consisting of streptavidin binding peptide (SBP) followed by GFP and GluK2, and a streptavidin-KDEL "anchor". The ER retention signal KDEL retains SBP-containing proteins in the ER. Upon addition of biotin to the cell culture medium, SBP-GFP-Gluk2 is released allowing its trafficking through the secretory pathway. B,C) The constitutively ER-retained SEZ6 mutant SEZ6∆cytoER-HA (B) and full length wild-type SEZ6FL-HA (C) were co-transfected with SBP-GFP-GluK2. Biotin was added to elicit release of SBP-GFP-GluK2 from the ER (0 min) and cells were fixed at different time points (0, 20 and 40 min). HA-tagged SEZ6FL and SEZ6∆cytoER transgenes were labeled with anti-HA (mouse) and anti-mouse-Alexa594 antibodies. Size bars represent 5 µm. D) Scatter dot plot represents number of vesicles per cell in SBP-GFP-GluK2 RUSH experiment with SEZ6∆cytoER-HA (control) or SEZ6FL-HA co-transfection. Vesicle counts from 15 to 28 cells per timepoint from 2 independent experiments with mean number of vesicles and error bars (SD) are shown. Mann-Whitney test was used to compare HA-tagged SEZ6FL and SEZ6∆cytoER at each time point. At 20 min ***p-value=0.0007, at 40 min ****p-value<0.0001.
