Figure 2A. Uniform Manifold Approximation and Projection (UMAP) representation of monocyte subpopulations. B. Heatmaps representing different monocyte clusters identified by FlowSOM, with percentages in healthy donors (CTR) and COVID-19 patients. The colors in the heat map represent the median of the arcsinh, 0-1 transformed marker expression calculated over cells from all the samples, varying from blue for lower expression to red for higher expression. Each cluster has a unique color assigned (bar on the left which colors correspond to those used in panel A). C. Differential analysis between healthy donors (CTR, n=8) and COVID-19 (COVID, n=7). The heatmap represents arcsine-square-root transformed cell frequencies that were subsequently normalized per cluster (rows) to mean of zero and standard deviation of one. The color of the heat varies from blue, indicating relative under-representation, to red indicating relative over-representation. Bar and numbers at the right indicate significant differentially abundant clusters (green) and adjusted p values (Differential analysis performed by diffcyt package present in the Catalyst package). The statistical analyses was done using GLMM (according to the actual guidelines) and all p-values were Bonferroni corrected. Clusters were sorted according to the adjusted p values, so that the cluster at the top shows the most significant abundance changes between the two conditions. D. Boxes and whiskers plots representing maximum, minimum, median value, 25 and 75 percentile of different subpopulations of monocytes in healthy donors (CTR, n=8) and COVID-19 patients (COVID, n=7). E.

Rag GTPases regulate recruitment of MITF and TFEB to lysosomes.Figure 9.(A and B) ARPE-19 cells were nucleofected with the indicated Rag- and MITF-expressing plasmids. 12 h later, cells were fixed, permeabilized with 0.2% Triton X-100, and double stained with antibodies against FLAG and GST (used to detect MITF and Rag proteins, respectively). Bars, 10 µm. (C) Model representing the mechanism of TFEB and MITF regulation by Rag GTPases. (top) In nutrient-rich conditions, active Rags promote recruitment of mTORC1 and TFEB to lysosomes, thus facilitating mTORC1-dependent phosphorylation of TFEB. Phosphorylation of TFEB at S211 creates a binding site for 14-3-3 and results in sequestration of TFEB in the cytosol. We suggest that 14-3-3 may mask the Rag-binding domain in TFEB (represented in yellow). (bottom) In the absence of amino acids, Rag GTPases and mTORC1 are inactivated. Dissociation of the TFEB-14-3-3 complex allows transport of TFEB to the nucleus and TFEB-mediated activation of a transcriptional network that promotes autophagy, lysosomal biogenesis, and increased lysosomal degradation. Our model proposes that some MITF isoforms might be regulated in a similar manner. The interaction of MITF-1 with 14-3-3 has been previously described (Bronisz et al., 2006). Please note that mTORC1-dependent phosphorylation of MITF-1 S280 has not been reported and is merely speculative. The representation of the Ragulator-Rag-mTORC1 complex is based on the recent crystal structured described by Gong et al. (2011). P, phosphorylation.
Figure 3(A) Tetrad analysis reveals that the respiration defect of Sc+Sb-CCM1 cells can be rescued by mutations in mitochondrial or nuclear genomes. The suppressor clones were crossed with the Sc+Sb-CCM1-ρ⁰ strain and the tetrads from the cross were analyzed. A non-Mendelian 4:0 segregation pattern for improved respiration is expected if the suppressor mutation is in mtDNA (left panel). Otherwise, a 2:2 segregation pattern would be observed if the rescue effect involved a single nuclear mutation (right panel). (B) Partial sequence alignment of 15S rRNA from S. bayanus, S. cerevisiae and two mitochondrial suppressor clones (#1 and #2) of Sc+Sb-CCM1. A single-nucleotide deletion at position 188 and four nucleotide substitutions at positions 1524-1527 found in both suppressor clones are labeled in red.

Figure 3(A-B) NIH 3T3 cells were (A) co-transfected with constructs expressing full length SPOP and GFP-Gli31455 or (B) transfected with a construct expressing SC-35-GFP, and GFP fluorescence was monitored in live cells. (A) Snapshots were taken from individual timepoints as noted in the Figure to show photobleaching (at 0 s), recovery, and nuclear body fusion events. The arrow in each panel points to the body that was photobleached and subsequently fuses with another body. These data were not used to calculate the average recovery time as the fusion event precludes accurate measurement of fluorescence recovery.

Data from 45 individual cells and FRAP events were corrected for background, normalized to the minimum and maximum intensity, and the mean is shown with error bars representing the standard error of the mean.

Residues mutated in this study are highlighted with circles. B. Size Exclusion Chromatography (SEC) and SEC-MALS (SEC combined with Multi Angle Light scattering) analyses of the recombinant wild-type (wt) and dimer disrupting mutant (I31A) of spMis181-120.

Evaluation of the ability of Yippee-like domains of human Mis18 proteins (hsMis18α77-187 and hsMis18β56-183) to form a heterodimer.

Purified hsMis18α77-187 and hsMis18β56-183 when mixed together elute at 15.4 ml as a heterodimer (27.5 kDa). D.
