The iProClass database provides value-added information reports for UniProtKB and unique NCBI Entrez protein sequences in UniParc, with links to over 170 biological
databases, including databases for protein families, functions and pathways, interactions, structures and structural classifications, genes and genomes, ontologies, literature, and taxonomy.
iProClass combines both data warehouse and hypertext navigation methods for integrating data, providing a comprehensive picture of protein properties that may lead to novel prediction and functional inference for previously uncharacterized "hypothetical" proteins and protein groups.
iProClass is implemented in Oracle system, and can be used to support protein sequence annotation and genomic/proteomic research, to obtain comprehensive up-to-date information on proteins and, in addition, to protein ID mapping (Wu et al., 2004).
