Implementing Databases (3)
MIPModDB: A Central Resource for the Superfamily of Major Intrinsic Proteins
This is a database of comparative protein structure models of MIP (Major Intrinsic Protein) family of proteins. The nearly completed sets of MIPs have been identified from the completed genome sequence of organisms available at NCBI. The structural models of MIP proteins were created by defined protocol. The database aims to provide key information of MIPs in particular based on sequence as well as structures. This will further help to decipher the function of uncharacterized MIPs.

PASS2 contains alignments of structural motifs of protein superfamilies. PASS2 is an automatic version of the original superfamily alignment database, CAMPASS (CAMbridge database of Protein Alignments organised as Structural Superfamilies). PASS2 contains alignments of protein structures at the superfamily level and is in direct correspondence with SCOPe 2.04 release.

Integrated resource of protein families, domains and functional sites
InterPro is an integrated database of predictive protein "signatures" used for the classification and automatic annotation of proteins and genomes. InterPro classifies sequences at superfamily, family and subfamily levels, predicting the occurrence of functional domains, repeats and important sites.
