a database of protein disorder and mobility annotations

Description of the database


Disordered protein regions are key for the function of numerous processes within an organism, and the determination of the protein's biological role. The current most common sources for protein disorder annotations, DisProt and the PDB, cover only a fraction of the available sequences in the SwissProt database and up to this date deal only with X-Ray resolved structures.

MobiDB's motivation is to build on the content provided by those sources and expand it, with the goal of providing a centralized source for data on disordered regions in protein structures, featuring full coverage of the SwissProt database.

Three different sources of raw data and four different flavors of disorder are included and available -featuring a novel NMR mobility definition- and its flexible design makes the addition of extra annotating sources (e.g. mobility/disorder predictors) a simple task.

Precalculated annotations from three disorder predictors (ESpritz, IUPred and DisEMBL) are also included to provide information in cases where experimental annotations are not available.


Use cases


There are two main use cases for MobiDB: the first, analyzing a single protein and generating consensus annotations based on different sources of information. The second, generating a dataset of a protein ensemble of certain characteristics for offline analysis, which will include all available annotations.
