Subcellular localization of proteins is essential in the spatial and temporal organisation of biological processes. Translocating proteins play a key role in the reconfiguration of cellular functions after environmental changes, as well as in embryonic or disease development. Protein translocation as a systems biology phenomenon, refers to the regulated movement of a protein between subcellular compartments. Translocation changes the interaction partners and leads to altered function(s) of translocating proteins. Though several protein translocations are well characterized, the systematic analysis of this phenomenon was still missing.
The Translocatome database (translocatome.linkgroup.hu) contains 213 manually curated human translocating proteins. The database contains information about the details of the translocating proteins’ structure, localization, regulation and interacting partners. Based on the manually curated proteins we implemented a machine learning algorithm using the XGBoost learning algorithm. To predict the translocation probabilities of 13 066 human proteins we used 139 human non-translocating proteins as a negative learning set and annotated each protein in our database with functional (Gene Ontology) and network parameters. With this method, we identified 1133 high-confidence and 3268 low-confidence translocating proteins.
The Translocatome database enables a systematic analysis of protein translocation. Thus, we’ll be able to better understand the role translocating proteins play in cellular behaviour and certain cellular disfunctions. As translocating proteins play a key role in cancer progression the better understanding of this phenomenon may lead to the recognition of new therapeutic targets.
