Description of the data and file structure

We performed a large-scale PAR-binding screen using a human protein microarray to identify proteins that interact non-covalently with poly(ADP-ribose) (PAR). This experiment characterized the PAR-binding proteome (PARylome) and identified 356 PAR-binding proteins involved in diverse biological processes beyond DNA damage and repair, providing a global resource for studying PAR-mediated regulation.

Files are labeled by figure and include imaging files, data sets in Excel, and graphs in GraphPad. All files included in this submission are raw data files generated from experiments performed for this manuscript.

File RS00283659.gal is used for the protein chip reference (Protein coordinate mapping file).

Two files, "20111123 test chip.tif" and "20111123 test chip2.tif", were used for initial background setup and chip quality test. Each raw file (.tif), scanned using a GenePix 4000 scanner, can be loaded into GenePix Pro software (user guide: https://www.moleculardevices.com/sites/default/files/en/assets/data-sheets/br/genepix-pro-7-software.pdf) to extract the corresponding images for Anti-mouse Alexa488 and Anti-rabbit Alexa594. From this, the relevant data tables can be generated.
