Protein phosphorylation evolution across 18 fungal species

Subscribe Comment Reanalyze Spectra Add Reanalysis

Description

Protein phosphorylation evolution across 18 fungal species. For each species whole cell extracts were digested separately with trypsin and LysC. Each digest was IMAC enriched and analyzed by LC-MS/MS in technical triplicate on an LTQ Orbitrap Velos using a 120min method. Data was searched against the corresponding species using Sequest/Comet, and filtered to 1% FDR at the PSM level. For S.Cerevisiae, S.Pombe and S.Mikatae, cells were grown in triplicate under 3 different conditions: YPD, YPD + mild temperature stress and optimized "best media". For these cells whole cell extracts were produced, digested with trypsin and IMAC enriched and analyzed by LC-MS/MS on an LTQ Orbitrap Velos using a 120min method. Data was searched against the corresponding species using Sequest/Comet, and filtered to 1% FDR at the PSM level. S. cerevisiae cells transformed with tagged versions of CDC33 WT, alanine (S28A) and glutamic acid (S28E) mutants were generated. Mutant strain were grown three distinct (heavy, medium and light) SILAC media under overexpression conditions. Cells for each construct were harvested and pooled together and used for the pull down experiments, done in triplicate. Pulldown eluate was digested with LysC and analyzed on a QExactive instrument with 90min method. Data was searched against S.Cerevisiae database including the tagged CDC33 proteins using Sequest/Comet, and filtered to 1% FDR at the PSM level. [dataset license: CC0 1.0 Universal (CC0 1.0)]

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.
