Bioinformatics Research Guide: Proteomics Databases


netXtProt is a database of the human proteome containing information on over 20,000 human proteins, the vast majority of which their existence has been determined through direct identification or through the identification of their mRNA transcripts. neXtProt offers the ability to identify proteins through their name, DNA, amino acid sequence, and chromosome of origin. neXtProt also allows for the more in depth study of protein variants of ion channels, kinases, and proteins associated with cancer.

Protopedia is a wiki style database containing information on a wide array of biological macromolecules. The site offers generalized information about the molecule of interest in addition to providing 3D visuals on the structure of the molecule and information on its interactions, locations, and targets. As a wiki style platform Protopedia allows for the community to add information based on their research and publications and seeks to provide the information in a way to aid others in research and facilitate the teaching of students.

Protein Data Bank

The Protein Data Bank is a database of proteins and nucleic acids. The site offerers scientists and educators the ability to both upload new information on known sequences and proteins or completely novel entities, and download sequence and other scientific information as well. The database allows for searching based on sequence, function, ligand, and drug targets as well as offering visual representations of the 3D structure of proteins, the pathways they are involved in, mechanism of drug and ligand interaction, and where their sequence lies on human chromosomes.

Human Protein Atlas

The Human Protein Atlas is a database containing the location of all known human proteins with three major sub-divisions. The Tissue Atlas showing the protein expression levels and their localization in all human tissues, the Cell Atlas shows the expression and sub-cellular localization of proteins in 64 human cell lines, the Pathology Atlas shows the abhorrent expression patterns of proteins in 18 different types of human cancers. In addition to these Atlases the database contains information on wide classes of human proteins, protocols and methods for human protein experimentation ,and access to antibodies and cell lines for research.

STRING is a proteomic database focusing on the networks and interactions of proteins in a wide array of species. STRING allows for the searching of one or multiple proteins at a time with the ability to additionally limit the search to the desired species. STRING's results shows visual representations of the interactions that the searched protein is involved in along with expression, location, transcription, and experimental data on the protein and its associated proteins.
