All SAXS data collection was performed at the SIBYLS beamline, an international user facility. An application for experiments is accessible at www.bl1231.als.lbl.gov. The data collection strategy has been designed to minimize errors due to instrumentation, radiation damage and concentration dependant phenomenon. The strategy applied depended on available stock concentration and size of the protein. SAXS data were collected on 3 serial dilutions of each sample preparation starting at a maximum 10 and a minimum of 1 mg/ml. Sample loading for data collection for each protein proceeded in the following order, lowest concentration, middle concentration, highest concentration followed by a final buffer measurement. The sample cell was washed between protein solutions using a mild detergent soak for 1 minute followed by 3 rinses with buffer solution. The subtraction of buffer collected before the sample was compared to buffer collected after each sample to insure the subtraction process was not subject to instrument variations. Data was collected from two short and one long X-ray exposure for each protein sample. The short exposures were compared against one another to identify whether significant radiation damage occurred on this time scale. The beam size at the sample is 4×1mm and converges at the detector to a 100×100µm spot. The large beam size at the sample spreads radiation over the entire sample greatly reducing radiation damage. Concentrations were compared against one another to determine whether concentration dependant structure factors contributed to the data. In two cases minor concentration dependence was observed and corrected by extrapolating behavior to zero concentration9 using code developed in house. A final scattering curve used for analysis was created for each sample (Supplementary Figure 2).
For most samples only 1 Å X-rays were used. Short exposures were 0.5 seconds while the long exposures were 5 seconds. However for proteins with long dimensions such as PF1548, 1.5 Å wavelength was also used to better define the maximum distances. Short and long exposures were 4 and 40 seconds respectively. All data were collected at room temperature.

Most keywords with which UniProt proteins are annotated were originally defined manually by database curators. They are automatically transferred to homologous proteins according to various rules developed within UniProt (1 (link)). The keyword annotation similarity between two proteins x, y with keyword lists Kx and Ky is defined in the exact same way as the GO annotation similarity while defining sim(a, b) = I(a = b), with indicator function I( · ). This yields sim(x, y) = 2|KxKy|/(|Kx| + |Ky|). The keywords in the UniProt knowledge base describe functional features in categories such as molecular function, domain, biological process, ligand and cellular component. We ignore keyword categories technical term and coding sequence diversity, and keywords provided by the UniProt automatic annotation team that do not describe biological functions.

The effects of mutations on the kinase and TF activities were assessed by associating the activity of a given protein with the mutational status of the same protein or other proteins it might interact throughout the cellular regulatory networks. First, we built a binary mutation matrix M where the index Mij corresponds to 1 if the sample i has a mutation in gene j and 0 otherwise. To do that, we selected the mutations classified as frameshift and in‐frame Indels, missense, nonsense and stop codon loss. Given the proteins X and Y, the association between the activity of Y (Yact) and the mutational status of X (Xmut) was assessed across samples by fitting a linear model that took into account possible confounding effects: Yact=β0+β1Study+β2Xmut+ɛ where Yact represents the activity of protein Y, β0 the intercept, β1 the regression coefficient for the covariate experimental study, β2 the regression coefficient for the mutational status of X and ɛ the noise term. This model was applied to assess the effect of Xmut on the activity of the same protein (Xact ∼ Xmut) and on the activity of other proteins (Yact ∼ Xmut). The P‐values from the coefficients of Xmut (β2) were calculated using the t‐statistic over a Student's t‐distribution and adjusted for false discovery rate (FDR) using the Benjamini–Hochberg method. The linear models and respective statistics were calculated using the lm and p.adjust R functions.
The associations were performed with the genes mutated in more than 20 samples and with the protein activities estimated in at least 10 samples. An association between a pair Yact ∼ Xmut or Xact ∼ Xmut was performed if Xmut was mutated in at least five of all the samples in the pair. Regarding the Yact ∼ Xmut associations, we tested 520,938 pairs between 208 kinases and 3,590 genes and 1,048,216 pairs between 292 TFs and 3,590 genes. In relation to the Xact ∼ Xmut associations, we tested 40 pairs and 64 pairs with the kinases and TFs, respectively.

Surveillance, Epidemiology, and End Results (SEER) 18 Regs custom Data (1975–2016) is the data source for this retrospective study. We identified patients diagnosed stage III esophageal cancer from 2004 to 2015 (Fig. 1). Patients included in this exploration had to meet all of the criteria over 18 years of age, tumor size <600 mm, diagnosed with stage III esophageal cancer. The exclusion criteria were as follows not first malignant primary indicator, complete data could not be obtained, patients diagnosed by autopsy. We extracted the following data from the SEER database: age, primary site of tumor, histologic, race, gender, chemotherapy history, T stage, N stage, surgery history, radiation history, tumor size, marital status, radiation sequence with surgery, and follow-up information. We employed OS and cancer-specific survival rate (CSS) as survival rate times analyzed in this investigation. OS is the survival rate time from the day of diagnosis to the day of death from any cause or last follow-up. CSS is an OS measure excluding other causes of death. In this research, we adopted the AJCC 6th edition TNM staging. We use data from public databases and was exempt from institutional review board approval.

The PEHSS cohort was a feasibility study to investigate different approaches of starting ART in infants infected with HIV (5 (link), 44 (link)) that was undertaken in 2002–2005, prior to implementation of universal ART in all infants infected with HIV. We evaluated participants randomized to arm B, who received immediate ART from birth to 12 months followed by ATI. ART was restarted after ATI according to the prevailing 2003 WHO and South African national guidelines. To investigate T cell markers associated with disease progression or time to meeting ART criteria, we used PBMCs from 13 participants who were virally suppressed from whom samples were available up to 3 months before ATI. Multiple samples from 2 study participants, PS-021-C and PS-114-C, were obtained for the longitudinal study.
In addition, we investigated the immunophenotype of PD-1–expressing CD8+ T cells in older children and young adults from previously described cohorts in sub-Saharan Africa. PSPs were defined as children who were infected with HIV, ART-naive, and older than 5 years with CD4+ T cell counts of more 350 cells/mm3 and more than 20%; pediatric progressors were defined as having CD4+ T cell counts of less than 350 cells/mm3 or less than 20%. Viremic adults (viremic adults) consisted of horizontally infected ART-naive individuals with chronic infection matched by sex. The fourth group consisted of HIV-exposed uninfected children matched by age and sex. No data were available on viral load and drug suppression for the mothers of these children. In analyses done after ART initiation, samples were selected from the time point after 1 to 2 years of viral suppression.

The HIVDEP sgRNA library is composed of 525 genes (4,191 sgRNAs). The top scoring 368 genes (as determined by -log10 MAGeCK score) of the genome-wide screen were included in the HIVDEP library. Additional unique top scoring genes with <10%FDR from HuEpi and PIKA screens were added to the HIVDEP library that contained an additional 131 genes. NR5A1, NHLRC4, SFTPA2, ZNF768, MYL10, GIMAP5, SPG21, CHSY3, ZNF25, REG1A, and ATXN3 were manually selected as nonessential genes (18 (link)) that were neither enriched nor depleted in the genome-wide screen. Six new sgRNAs were designed using two algorithms, GUIDES (52 (link)) and CHOPCHOP (53 (link)). We also manually included other known dependency factors, including CCR5 and PAPSS1. A total of 212 nontargeting controls were designed using GUIDES and included. The HIVDEP sgRNA library was synthesized (Twist Biosciences) and cloned into HIV-CRISPR. Oligo pools were amplified using Herculase II Fusion DNA polymerase (Agilent; 600677) combined with 1 ng of pooled oligonucleotide template, primers ArrayF and ArrayR (ArrayF primer: TAACTTGAAAGTATTTCGATTTCTTGGCTTTATATATCTTGTGGAAAGGACGAAACACCG and ArrayR primer: ACTTTTTCAAGTTGATAACGGACTAGCCTTATTTTAACTTGCTATTTC TAGCTCTAAAAC), an annealing temperature of 59°C, an extension time of 20 s, and 25 cycles. Following PCR amplification, a 140-bp amplicon was gel-purified and cloned into BsmBI (NEB; R0580) digested HIVCRISPR using Gibson Assembly (NEB; E2611S). Each Gibson reaction was carried out at 50°C for 60 min. Drop dialysis was performed on each Gibson reaction according to the manufacturer’s protocol using a Type-VS Millipore membrane (VSWP 02500). Then, 5 μL of the reaction was used to transform 25 μL of Endura electrocompetent cells (Lucigen; 60242-2) according to the manufacturer’s protocol using a Gene Pulser (Bio-Rad). To ensure adequate representation, sufficient parallel transformations were performed and plated onto carbenicillin containing LB agarose 245 × 245 mm plates (Thermo Fisher) at 492-times the total number of oligonucleotides of each library pool. After overnight growth at 37°C, colonies were scraped off, pelleted, and used for plasmid DNA preps using the endotoxin-free Nucleobond plasmid midiprep kit (TaKaRa Bio; 740422.10). The HIVDEP library was sequenced and contains all 4,191 sgRNAs included in the synthesis (GEO Data set, accession numbers GSM6945645 and GSM6945646).
