The Human Protein Reference Database (HPRD) is a protein database accessible through the Internet.[1] It is closely associated with the premier Indian Non-Profit research organisation Institute of Bioinformatics (IOB), Bangalore, India. This database is a collaborative output of IOB and the Pandey Lab of Johns Hopkins University.

Overview

The HPRD is a result of an international collaborative effort between the Institute of Bioinformatics in Bangalore, India and the Pandey lab at Johns Hopkins University in Baltimore, USA. HPRD contains manually curated scientific information pertaining to the biology of most human proteins. Information regarding proteins involved in human diseases is annotated and linked to Online Mendelian Inheritance in Man (OMIM) database. The National Center for Biotechnology Information provides link to HPRD through its human protein databases (e.g. Entrez Gene, RefSeq protein pertaining to genes and proteins.

This resource depicts information on human protein functions including protein–protein interactions, post-translational modifications, enzyme-substrate relationships and disease associations. Protein annotation information that is catalogued was derived through manual curation using published literature by expert biologists and through bioinformatics analyses of the protein sequence. The protein–protein interaction and subcellular localization data from HPRD have been used to develop a human protein interaction network.[2]

Highlights of HPRD as follows:

HPRD also integrates data from Human Proteinpedia, a community portal for integrating human protein data. The data from HPRD can be freely accessed and used by academic users while commercial entities are required to obtain a license for use. Human Proteinpedia[5] content is freely available for anyone to download and use.

PhosphoMotif Finder

PhosphoMotif Finder[6] contains known kinase/phosphatase substrate as well as binding motifs that are curated from the published literature. It reports the PRESENCE of any literature-derived motif in the query sequence. PhosphoMotif Finder does NOT PREDICT any motifs in the query protein sequence using any algorithm or other computational strategies.

Comparison of protein data

There are other databases that deal with human proteome (e.g. BioGRID, BIND, DIP, HPRD, IntAct, MINT, MIPS, PDZBase and Reactome). Each database has its own style of presenting the data. It is a difficult task for most investigators to compare the voluminous data from these databases in order to conclude strengths and weaknesses of each database. Mathivanan and colleagues [7] tried to address this issue while analyzing protein data by asking various questions. This analysis will help biologists to choose among these databases based on their needs.
