The Proteomic-Genomic Nexus (PG Nexus) is a Java-based software package that is designed to integrate genomic and transcriptomic data generated from next-generation sequencing with proteomic data generated from protein mass spectrometry. The tools were built by Intersect Australiaas part of an ANDS-funded project within the Applications Programme.
By using the PG Nexus, users will be able to:
- Co-visualise genomics, transcriptomic and proteomic data using the Integrated Genomics Viewer(IGV).
- Validate the existence of genes and mRNAs using peptides identified from mass spectrometry experiments.
- Validate alternatively spliced mRNA isoforms by searching for peptides that span across exon-exon junctions.
Download the PG Nexus via GitHub.

Introduction to the PG Nexus:
- Database and input files for the PG Nexus can be downloaded here.These files were used to validate protein isoforms with RNA-Seq data.
- The human genome (version Hg19) downloaded here. It is formatted with one chromosome per FASTA file and is compatible with the pipeline.
- The human genome (version 75) can be downloaded here. These files were used to validate protein isoforms with RNA-Seq data.
