Protein Database is a collection of sequences from several sources, including translations from annotated coding regions in Gen Bank, Ref Seq as well as records from SWISS-PROT, PIR & PDB.

Finds regions of local similarity between sequences.

Compares nucleotide or protein sequences to sequence databases.

Calculates statistical significance from matches.

Can be used to infer functional and evolutionary relationships between sequences.

It can also help in identifying members of the gene family.

PIR was established in 1984 by the National PIR was established in 1984 by the National Biomedical Research Foundation (NBRF) as a Biomedical Research Foundation (NBRF) as a resource to assist researchers in the resource to assist researchers in the identification and interpretation of protein identification and interpretation of protein sequence information.sequence information.

PIR has provided many protein databases PIR has provided many protein databases and analysis tools freely accessible to the and analysis tools freely accessible to the scientific community, including the Protein scientific community, including the Protein Sequence Database (PSD).Sequence Database (PSD).
