The PIR-PSD, Current Entries.
The Protein Information Resource (PIR), in collaboration with MIPS and JIPID, produces the PIR-International Protein Sequence Database (PIR-PSD) -- a comprehensive, non-redundant, expertly annotated, fully classified and extensively cross-referenced protein sequence database in the public domain. The PIR-PSD, PIR-NREF, iProClass and other PIR auxiliary databases provide an integration of sequences, functional, and structural information to support genomics and proteomics research.
