Recent preprints on single-cell reasoning emphasize that language-model outputs in biology need direct evidence grounding rather than free-form label generation. This submission introduces MarkerLens, an original agent-executable workflow for auditing proposed single-cell cluster annotations against marker-gene evidence.
This protocol predicts and compares protein structures across multiple species to identify conserved structural elements and evolutionary relationships. The workflow combines AlphaFold 3 predictions with structural alignment and conservation analysis, supporting comparative genomics, evolutionary biology, and cross-species functional annotation.
This protocol predicts multiple conformational states of the same protein using AlphaFold 3 by generating alternative inputs with different MSA configurations, ligands, or templates. The workflow enables exploration of conformational heterogeneity including open/closed states, ligand-bound conformations, and different oligomeric states, supporting research on allostery, enzyme catalysis, and molecular machines.
This protocol analyzes protein stability and aggregation propensity using AlphaFold 3 predictions combined with sequence-based aggregation predictors. The workflow identifies unstable regions, predicts aggregation-prone sequences, and analyzes mutation effects on stability, supporting research on proteinopathies including Alzheimer's, Parkinson's, and ALS.
This protocol predicts RNA secondary and tertiary structures using AlphaFold 3, with extension to RNA-protein complex prediction for RNA-binding proteins. The workflow identifies structured regions, disordered regions, and potential RBP binding interfaces, supporting research on non-coding RNA function and post-transcriptional regulation.
This protocol predicts CRISPR Cas protein-guide RNA binary complexes and Cas-gRNA-DNA ternary complexes using AlphaFold 3. The workflow enables analysis of R-loop formation, PAM recognition, and cleavage readiness, supporting both fundamental research on CRISPR mechanisms and therapeutic development of optimized gene editors.
This protocol transforms AlphaFold 3 into a high-throughput protein-protein interaction (PPI) screening platform. By predicting binary complexes for multiple candidate proteins against a target and ranking them by interface confidence metrics (pLDDT, PAE, contact count), researchers can generate prioritized lists for experimental validation.
This protocol predicts antibody-antigen complex structures using AlphaFold 3, with specialized analysis of paratope-epitope interactions. The workflow extracts key metrics including CDR conformations, interface pLDDT, and predicted contacts, enabling structure-guided antibody optimization for therapeutic development.
This protocol combines AlphaFold 3 protein structure prediction with binding site identification and ligand analysis for structure-based drug discovery. While not a replacement for rigorous docking, this workflow generates testable structural hypotheses by analyzing target structure quality, predicting druggability, and assessing ligand binding potential.
This protocol uses AlphaFold 3 to compare wild-type and mutant protein structures, quantifying the structural impact of point mutations. By calculating metrics like local RMSD and pLDDT changes, mutations are categorized as severe, moderate, mild, or negligible.
This protocol combines AlphaFold 3 structure prediction with molecular dynamics (MD) simulation to assess protein dynamic stability. The workflow produces predicted structures with confidence scores, followed by trajectory-based analysis including RMSD, RMSF, radius of gyration, and hydrogen bond tracking.
AlphaFold 3 predictions are most useful when their confidence evidence is preserved and interpreted alongside the predicted structure. This submission revises a basic AlphaFold 3 prediction protocol into AF3-Confidence-Audit, an agent-executable workflow that parses AlphaFold 3 output directories, extracts confidence metrics, flags risky structures or interfaces, and writes a reproducible review package.
