CRISPR-Cas-Docker

CRISPR-Cas-Docker predicts optimal crRNA–Cas protein interactions by combining in silico structure-based docking and sequence-based machine learning classification to assign crRNAs to Cas systems in prokaryotic and metagenomic datasets.

Key Features:

• In Silico Docking: Performs structure-based docking of crRNAs and Cas proteins using either experimentally determined 3D structures or predicted 3D structures generated by the tool's pipeline.
• 3D Structure Prediction: Generates predicted 3D structures for crRNAs and Cas proteins when experimental structures are not provided.
• Machine Learning Classification: Applies a sequence-based machine learning classifier to predict the optimal Cas protein for a given crRNA sequence.
• Optimization for RNA–Protein Interactions: Implements computational optimizations targeted at evaluating and ranking RNA–protein interactions within CRISPR–Cas systems.

Scientific Applications:

• RNA–Protein Interaction Prediction: Predicts crRNA–Cas protein binding preferences to inform experimental validation of RNA–protein interactions.
• Assignment in Metagenomic Data: Assigns crRNAs to cognate Cas systems in prokaryotic genomes and metagenomic assemblies containing multiple CRISPR arrays and Cas proteins.
• Microbial Genetics and Evolutionary Studies: Supports studies of CRISPR–Cas system distribution and evolution by providing interaction and assignment predictions.

Methodology:

Performs structure-based in silico docking between crRNAs and Cas proteins, generates predicted 3D structures when experimental models are not provided, and applies sequence-based machine learning classification to predict optimal Cas proteins for given crRNA sequences.
