Description

Time-resolved proteomic profiling of SGs from cultured human U2OS cells over a prolonged heat-shock (HS) and a successive recovery period, sampling at the 6 time points of HS exposure (10, 20, 30, 60, 120, 180 min), as well as 2 time points of recovery (5, 10 min). From the sampled cells, we prepared SG samples using a differential centrifugation plus endogenous G3BP1 immunoprecipitation protocol. Peptides were subsequently TMT-labeled and analyzed by quantitative LC-MS/MS. In G3BP1 dataset, rep1-rep3, HS-10, 20, 30, 60, 120, 180, re5, re10, SG-ls, G3BP1-IP samples were labeled with TMT-126, 127N, 127C, 128N, 128C,129N, 129C, 130N, 130C, 131 label Reagents, respectively; G3BP1_HS0 was a dataset created to integrate a non-heat shock control (HS-0) into the G3BP1 dataset, contains HS0, HS10, and HS60, and the results was integrated into the G3BP1 dataset using the ComBat processing, HS-0_rep1, HS-0_rep2, HS-0_rep3, HS-10_rep1, HS-10_rep2, HS-10_rep3, HS-60_rep1, HS-60_rep2, HS-60_rep3 samples were labeled with TMT-126, 127N, 127C, 128N, 128C,129N, 129C, 130N, 130C label Reagents, respectively. In CAPRIN1 dataset, rep1-rep3, HS-0, 10, 20, 30, 60, 120, 180, re5, re10 samples were labeled with TMT-126, 127N, 127C, 128N, 128C,129N, 129C, 130N, 130C label Reagents, respectively.

Click here to queue conversion of this dataset's submitted spectrum files to open formats (e.g. mzML). This process may take some time.

When complete, the converted files will be available in the "ccms_peak" subdirectory of the dataset's FTP space (accessible via the "FTP Download" link to the right).
Number of distinct conditions across all analyses (original submission and reanalyses) associated with this dataset.

Distinct condition labels are counted across all files submitted in the "Metadata" category having a "Condition" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct biological replicates across all analyses (original submission and reanalyses) associated with this dataset.

Distinct replicate labels are counted across all files submitted in the "Metadata" category having a "BioReplicate" or "Replicate" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct technical replicates across all analyses (original submission and reanalyses) associated with this dataset.

The technical replicate count is defined as the maximum number of times any one distinct combination of condition and biological replicate was analyzed across all files submitted in the "Metadata" category. In the case of fractionated experiments, only the first fraction is considered.

"N/A" means no results of this type were submitted.
Originally identified proteins that were automatically remapped by MassIVE to proteins in the SwissProt human reference database.

"N/A" means no results of this type were submitted.
Number of distinct protein accessions reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct unmodified peptide sequences reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct peptide sequences (including modified variants or peptidoforms) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Total number of peptide-spectrum matches (i.e. spectrum identifications) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins quantified across all analyses (original submission and reanalyses) associated with this dataset.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins found to be differentially abundant in at least one comparison across all analyses (original submission and reanalyses) associated with this dataset.

A protein is differentially abundant if its change in abundance across conditions is found to be statistically significant with an adjusted p-value <= 0.05 and lists no issues associated with statistical tests for differential abundance.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
This dataset may not contain all raw spectra data as originally deposited in PRIDE. It has been imported to MassIVE for reanalysis purposes, so its spectra data here may consist solely of processed peak lists suitable for reanalysis with most software.
