Motivation and solution

PTM parent proteins were not handled correctly when protein groups contained multiple members or GlobalProtein was "missing". The change adds PTM-site filtering and entity-value transfer for networks, and updates UniProt FASTA-header handling.

Changes

• Export filter_by_ptm_site() and add_entity_values().
• Add filter_by_ptm_site() to retain edges whose target node contains the edge’s PTM site. Remove nodes left without edges.
• Add add_entity_values() to transfer logFC and adj.pvalue values to matching network nodes, with optional overwrite behavior.
• Strip PTM-site suffixes from each protein-group member when deriving parent proteins. Replace missing GlobalProtein values with those derived parents.
• Parse UniProt accessions and mnemonics from FragPipe-style FASTA headers during ID conversion, while retaining the original header as the entity ID.
• Add a CPTAC CCRCC PTM and global-profiling example script and update the PTM vignette to use this workflow.
• Add documentation for the new functions and updated entity-preparation behavior.

Tests

• Add tests for PTM suffix removal across protein groups and replacement of "missing" GlobalProtein values.
• Add tests for accession and mnemonic extraction from FASTA headers.
• Add integration tests for PTM-site filtering, entity matching, overwrite handling, validation, network-element preservation, and data.table node compatibility.
• Test execution results were not provided.

Coding guidelines

• No coding-guideline violations or review findings were provided, so violations cannot be assessed.

📝 Walkthrough

The changes add UniProt FASTA-header parsing and PTM parent handling, introduce two network post-processing functions, and replace the PTM vignette with a CPTAC CCRCC workflow using phosphoproteomics and global-profiling data.

Changes: PTM Analysis

Layer / File(s)	Summary
Entity identifiers and PTM parents R/entities.R, R/backend-indra.R, R/annotateProteinInfoFromIndra.R, tests/testthat/test-entities.R, tests/testthat/test-backend-indra.R, tests/testthat/test-annotateProteinInfoFromIndra.R, man/prepare_entities.Rd, NEWS.md	UniProt FASTA headers are retained as entity IDs while conversion uses the accession or mnemonic. Missing, empty, or "missing" GlobalProtein values are populated from PTM parent identifiers, including protein groups.
PTM-site network filtering NAMESPACE, R/network-postprocess.R, man/filter_by_ptm_site.Rd, tests/testthat/test-ptm-integration.R	filter_by_ptm_site() keeps edges whose sites match sites on their target nodes and removes nodes left without edges. The shared edge helper also updates filter_by_curation().
Entity values on network nodes NAMESPACE, R/network-postprocess.R, man/add_entity_values.Rd, tests/testthat/test-ptm-integration.R, NEWS.md	add_entity_values() matches entities by ID and site, then by grounding and site. It adds statistics to matched nodes, supports optional overwrites, and creates protein-level rows when required.
CPTAC data and network analysis inst/script/cptac-ccrcc-network.R, vignettes/PTM-Analysis.Rmd, NEWS.md	The script saves converted CPTAC CCRCC data and phosphorylation networks. The vignette loads saved results, filters networks to measured target sites, adds global protein values, and visualizes the resulting network.

Merge Risk: 🔵 Low · up to 3908d

The CPTAC vignette can display stale network results after the script regenerates the source-tree RDS. This is limited to the analysis workflow and has a reinstall workaround, but the paths should be aligned before relying on the output.

And sorts the sites along the way.
The network keeps its matched edges,
Global values join the fray.
Then CPTAC blooms on screen today.}

- Around line 6-9: Update the CSV reads in this data-generation script to load
both generated files from the repository’s inst/extdata directory rather than
using system.file() to resolve installed-package copies; preserve the existing
file names and downstream processing.

Review comments at @R/annotateProteinInfoFromIndra.R:
- Around line 115-116: Update the `GlobalProtein` fallback assignment for
`no_global` rows to split each `Protein` group into members, strip each member
with `.stripPtmSite()`, and join the stripped parents before assignment so no
group member is omitted.
