PIR is a long-running public protein bioinformatics resource that historically contributed core sequence and annotation infrastructure to UniProt and continues to maintain protein-centric data integration and analysis resources. Its public site exposes databases, search tools, downloads, and supporting documentation for protein annotation workflows.
The ProKN products on this page are derived graph views built from PIR-linked protein mappings and cross-resource integration, including alignments to IMPC-derived gene and orthology data.
