PIMMS

PIMMS (Polymer Interactions in Multicomponent MixtureS) is a high-performance coarse-grained lattice-based simulation engine developed explicitly for studying phase transitions of complex heteropolymers, such as intrinsically disordered proteins. PIMMS was developed by Alex while in the Pappu Lab, and is a MOLSSI sponsored project.

SOURSOP

SOURSOP (Simulation analysis Of Unstructured and disordered RegionS Orchestrated in Python) is an integrative analysis suite for analyzing all-atom simulation trajectories of intrinsically disordered proteins. While SOURSOP was developed with CAMPARI Monte Carlo simulations in mind, it can be broadly used with almost any simulation engine and trajectory type.

The initial prototype for SOURSOP was developed by Alex while in the Pappu lab (as a MOLSSI-sponsored project) and completed by Pappu lab member Jared Lalmansingh.

SolutionSpaceScanner

SolutionSpaceScanner is a Python toolkit that includes a command-line tool for re-wiring the solvation behaviour of polypeptides by creating customizable parameter-files for the ABSINTH implicit solvent model. SolutionSpaceScanner was developed with the Sukenik lab at UC Merced and is a MOLSSI sponsored project.

GOOSE

GOOSE is a package for rationally designing disordered regions with specific sequence properties. The associated preprint will be online soon, but the code and documentation are already available. GOOSE was used in the design of sequence libraries for the ALBATROSS preprint, as well as several unpublished projects!

Preprint: Emenecker & Guadalupe et al. bioRxiv (2023)

Code: GitHub repository

Documentation: ReadTheDocs

Google Colab Notebook: Colab notebooks (in alpha - please report any issues!)

ALBATROSS

ALBATROSS is a collection of deep learning models that enable the direct prediction of disordered protein dimensions from sequence. ALBATROSS is implemented inside sparrow, our general sequence analysis framework. However, ALBATROSS predictions are also available via several Google colab notebooks, as well as via the metapredict.net webserver.

metapredict

metapredict is our high-performance, deep-learning-based disorder predictor. Metapredict provides both a Python API and a command-line tool for interacting with FASTA files or directly downloading sequences from the UniProt database. In addition, we provide a web server for individual sequences that can be accessed at http://metapredict.net/, and a Google colab notebook for multiple sequences.

Metapredict is a top-10 CAID predictor (see DISORDER-PDB) and many (many) orders of magnitude faster than other predictors with equivalent accuracy.

NOTE: As of May 2023 the default metapredict implementation has been updated to metapredict V2-FF. This is identical to metapredict V2 in terms of disorder predictions but offers dramatic improvements in performance on CPUs and GPUs.

Metapredict was developed by graduate students Ryan Emenecker and Dan Griffith.

Paper: Emenecker et al. Biophysical Journal (2021) and follow-up permanent preprint (Metapredict V2 - Emenecker et al. bioRxiv (2022)).
