Prosit - Deep learning model for proteomics

Prosit (https://www.proteomicsdb.org/prosit/) is a free to use deep learning framework for generating custom spectral libraries and iRT prediction and inferrence of high quality MS2 spectra for any organism and protease. Prosit is part of the ProteomeTools project and was trained on the project's high quality synthetic datasets.

Prosit has a wide range of functions, such as predicting spectra for proteases other than trypsin, generating spectral libraries for data-independent acquisition (DIA) and improving the analysis of metaproteomes. Prosit is integrated into ProteomicsDB, allowing search result re-scoring and custom spectral library generation for any organism on the basis of peptide sequence alone.

Tools utilizing Prosit

Oktoberfest

Oktoberfest is a python tool for collision energy calibration, rescoring search results and generating spectral libraries for proteomics research within the Prosit ecosystem. It offers an end to end pipeline that takes search results, predicts peptide properties using koina, plots summaries and quality control figures and performs FDR estimation with either mokapot or percolator.

Koina

Koina is a community driven endeavour to make AI models for life science research accessible. It is a service that tries to reduce the barrier of entry for using machine learning models in life science research by removing the need to set up and maintain the infrastructure required to run the models. The project is open-source and adheres to FAIR principles.
