=============================================================
**Phopsphoproteomic Enrichment Pipeline Preprocessing Steps**
=============================================================

*Overview*
==========

Prior to statistical analysis, it is necessary to perform
three steps to transform the MaxQuant output
for phosphoproteome-enriched samples.

*Workflow position*
===================

Upstream tool
=============

The input dataset for this tool is the ``Phospho (STY)Sites.txt`` file that is produced:

   - by the Galaxy "MaxQuant" (``maxquant``) tool
   - or by the Galaxy "Maxquant (using mqpar.xml)" (``maxquant_mqpar``) tool
   - or by the desktop version of MaxQuant.

Downstream tool
===============

The "MaxQuant Phosphopeptide ANOVA" tool (``mqppep_anova``) consumes the "preprocessed" output file ``preproc_tab`` that this tool produces.

*Phopsphoproteomic Enrichment Pipeline Localization-Probability Cut-Off*
========================================================================

This step applies a "localization-probability cut-off" for phosphopeptides for each phosphopeptide.
Higher values may reduce the number of peptides in the output.
The default value of 0.75 reflects the text of [Cheng  2018]:

    "For phosphopeptide identification, a localization probability cutoff is applied. This filter is performed to select for phosphopeptides with a high confidence (i.e., greater than 0.75) in phosphoresidue identification [Hogrebe 2018; Olsen 2006]. In other words, the summed probability of all other residues that could potentially contain the phospho-group is less than 0.25.  This cutoff could be raised to increase the stringency of the phosphopeptide selection. In regard to the number of identifications, the expected number of pY peptides is in the hundreds, while the expected number of pST peptides is in the high thousands. These values reflect previously observed phosphoproteome distribution where about 2%, 12%, and 86% of the phosphosites are pY, pT, and pS, respectively [Olsen 2006]."

This tool wraps an R script. written by Larry Cheng, that performs the following (in order):

1. Remove contaminant and reverse sequence rows
2. Filters rows based on localization probability
3. Extract the quantitative data
4. Inserts a "p" before the phosphorylated residue(s) in each peptide sequence
5. Merges (aggregating by "sum" or "average") multiply-phosphorylated peptides
6. Filters output phosphopeptides based on enrichment
7. Produces an output file (in tabular format) that contains the phosphopeptide (first column) and its (possibly merged) mass spectral intensity for each sample.

Note that the "ProTeomiX Quality Control Report"
[Bielow 2016] (available at `https://github.com/cbielow/PTXQC/
<https://github.com/cbielow/PTXQC/>`_) is run by the Galaxy wrappers for MaxQuant,
so it is omitted here even though it was included in Larry Cheng's original script.


Input dataset
=============

Phospho (STY)Sites.txt
   This is the ``MaxQuant Phospho (STY)Sites.txt`` file produced by MaxQuant.
   If you use the desktop version of MaxQuant, you will find this file in the ``txt`` folder.

Input parameters
================

Localization probability cutoff
  Minimum localization probability; see above.

Intensity merge-function
  Specifies how intensities for identical phosphosites should be merged. Choosing "sum" means that relative intensities reflect number of phospho-*residues*; choosing "average" means that relative intensities reflect number of phospho-*peptides*.

Output datasets
===============

``ppep_intensities``
  Data table (in tabular format) presenting, for each sample, the mass-spectral intensity of each phopshopeptide having localization probability greater than the cutoff.

``enrichment.pdf``
  Graph (in PDF format) presenting non-zero proportions of pS, pT, and pY among the phosphosites; note that a phosphopeptide may have multiple phosphosite.

``locProbCutoff.pdf``
  Graph (in PDF format) contrasting proportion of phosphopeptides above the localization probability cutoff with the proportion below.

``enrichment.svg``
  Enrichment graph (in downloadable "scalable vector graphics" format) for incorporation into documents.

``locProbCutoff.svg``
  Localization probability cutoff graph (in downloadable "scalable vector graphics" format) for incorporation into documents.

``filteredData``
  Data table (in tabular format) comprising rows of the ``phosphSites`` input file that are not flagged as contaminants or reversed sequences.

``quantData``
  Data table (in tabular format) comprising rows of the ``filteredData`` file whose localization probability exceeds the **Localization Probability Cutoff** parameter.

*Phopsphoproteomic Enrichment Pipeline Upstream Kinase Mapping*
===============================================================

This step searches phosphopeptides against several databases for known or predicted sites.

Input databases
===============

``networkin``
    This table is the result of filtering the NetworkKIN database [Linding 2007; Horn 2014] for cutoff score > 2.0.  The ENSEMBL data used to generate the file were from Ensembl, `ensembl.org <https://web.archive.org/web/20220308011159/http://useast.ensembl.org/index.html>`_ [Howe 2021].

To generate this file:

   (1) Download the "precomputed data for all available kinase predictors against ENSEMBL" (available at the NetworkKIN predictions link on the downloads page at https://web.archive.org/web/20200208000403/http://networkin.info/download/networkin_human_predictions_3.1.tsv.xz;  N.B.: "Commercial users are requested to contact the authors before using the data on the networkin.info website");
   (2) Decompress the .tsv.xz with file with "unxz" (from XZ Utils `https://tukaani.org/xz/ <https://tukaani.org/xz/>`_);
   (3) Filter out the rows having "network_kin" less than 2.0.

The result should be a tab-separated file with the following columns:

   - ``#substrate``
   - ``position``
   - ``id``
   - ``networkin_score``
   - ``tree``
   - ``netphorest_group``
   - ``netphorest_score``
   - ``string_identifier``
   - ``string_score``
   - ``substrate_name``
   - ``sequence``
   - ``string_path``


``p_sty_motifs``
   This database merges motif patterns from [Amanchy 2007] and Phosida [Gnad 2011].

     The Amanchy data are adapted from `https://web.archive.org/web/*/http://hprd.org/serine_motifs <https://web.archive.org/web/*/http://hprd.org/serine_motifs>`_ and `https://web.archive.org/web/*/http://hprd.org/tyrosine_motifs <https://web.archive.org/web/*/http://hprd.org/tyrosine_motifs>`_ (both links cite the reference where each motif was published), and the patterns are translated into Perl regular expression format (`https://perldoc.perl.org/perlre <https://perldoc.perl.org/perlre>`_).

   The Phosida data are adapted (translated to Perl-formatted regular expressions) from `http://pegasus.biochem.mpg.de/phosida/help/motifs.aspx <http://pegasus.biochem.mpg.de/phosida/help/motifs.aspx>`_ (this link cites the reference where each motif was published).

   This file has three tab-separated columns (and no header):

      - column 1 is an (ignored) identifier
      - column 2 is a Perl regular expression
      - column 3 is a descriptor.

   For two examples:

       ``2<TAB>R.R..(pS|pT)<TAB>Akt kinase substrate motif (HPRD)``

       ``10<TAB>R..(pS|pT)V<TAB>CAMK2_Phosida``

Output datasets
===============

``ppep_map``
  Data table (in tabular format, consumed by the merge/filter step) presenting, for each phosphopeptide, the kinase mappings,  the mass-spectral intensities for each sample, and the metadata from UniProtKB/SwissProt, phospho-sites, phospho-motifs, and regulatory sites.  Data in the columns marked "``Domain``", "``ON_...``", or "``..._PhosphoSite``" are available subject to the following terms:

``melted``
  Data table (in tabular format) presenting, for each phosphopeptide, the gene and one of the phospho-motifs or kinase-substrate sites.

``ppep_mapping_sqlite``
  SQLite database (consumed by the merge/filter step).
