The MIPS Mammalian Protein-Protein Interaction Database


The MIPS Mammalian Protein-Protein Interaction Database is a collection of manually curated high-quality PPI data collected from the scientific literature by expert curators. We took great care to include only data from individually performed experiments since they usually provide the most reliable evidence for physical interactions.

To suit different users needs we provide a variety of interfaces to search the database:

Background

Protein-protein interactions (PPI) represent a pivotal aspect of protein function. Almost every cellular process relies on transient or permanent physical binding of two or more proteins in order to accomplish the respective task. Comprehensive databases of PPI in Saccharomyces cerevisiae have proved to be invaluable resources for both bioinformatics and experimental research and are used heavily in the scientific community.

Although yeast is a well established model organism, not all interactions in higher eukaryotes have equivalent counterparts in unicellular systems. Currently, publicly available PPI databases contain comparatively few entries from mammals so we embarked on building a high-quality, manually curated database of protein-protein interactions in mammals.
