Aim
Protein Structure Prediction and Validation in Structural Biology trains participants to predict protein 3D structures using modern computational approaches (including AI-enabled methods) and to validate and interpret those structures responsibly for research. You’ll learn the end-to-end workflow—from sequence to model selection, confidence assessment, refinement concepts, and structure quality checks—so you can use predicted structures for hypotheses, docking preparation (intro), and structure-function insights without overclaiming.
Program Objectives
- Understand Structure Biology Basics: Secondary/tertiary structure, domains, folds, and functional motifs.
- Learn Prediction Approaches: Homology modeling, threading, ab initio concepts, and AI-based prediction workflows.
- Assess Model Confidence: Interpret confidence scores, alignment coverage, and uncertainty regions.
- Validate Structures Properly: Geometry, stereochemistry, clash checks, and Ramachandran analysis basics.
- Compare Models & Select Best: Ranking, consensus thinking, and use-case-based model selection.
- Prepare Structures for Downstream Use: Cleaning, chain/ligand handling, protonation concepts (intro).
- Communicate Limitations: Report what predicted models can support (and what they cannot).
- Hands-on Application: Complete a capstone: predict + validate a protein structure and produce a report.
Program Structure
Module 1: Structural Biology Essentials (What You Must Know First)
- Protein structure hierarchy: primary → secondary → tertiary → quaternary.
- Common elements: helices, sheets, loops, domains, intrinsically disordered regions (IDRs).
- Experimental structures: X-ray, NMR, Cryo-EM (what “resolution” means conceptually).
- Why predicted structures are useful: hypothesis generation, mutation mapping, design planning.
Module 2: From Sequence to Templates (Database & Alignment Thinking)
- Sequence quality checks: isoforms, signal peptides, low complexity, missing regions.
- Homology basics: identity, similarity, coverage, and why alignment matters most.
- Template discovery concepts: structural databases and template selection logic.
- Multiple sequence alignment overview for conserved regions and domain boundaries.
Module 3: Structure Prediction Approaches (Classical + AI Workflows)
- Homology modeling: building from templates (workflow view).
- Threading/fold recognition: when templates are weak (conceptual).
- Ab initio principles: conformational search and energy landscapes (high-level).
- AI-based prediction: what it predicts well vs where uncertainty remains (balanced view).
Module 4: Model Confidence & Practical Interpretation
- Per-residue confidence concepts: identifying reliable cores vs flexible regions.
- Domain-wise quality: split-domain modeling when needed (conceptual).
- Common failure zones: loops, termini, disordered segments, multi-domain orientations.
- Choosing models based on intended use: mutation mapping vs docking vs epitope planning (intro).
Module 5: Structure Validation (Quality Checks That Matter)
- Stereochemistry basics: bond lengths/angles, planarity, chirality (intro).
- Ramachandran plots: what “allowed regions” mean and how to read outliers.
- Clashes and packing: steric clashes, rotamers, and common artifacts.
- Global vs local quality: model scores vs residue-level issues.
Module 6: Refinement & Cleanup for Downstream Analysis (Intro)
- Energy minimization concepts and why “refinement” can help (or harm).
- Fixing issues: side-chain rotamers, missing atoms, protonation states (conceptual).
- Preparing structures: chain naming, removing waters/ions (if needed), formatting PDB/mmCIF.
- Quality documentation: what changes you made and why.
Module 7: Comparing Models, Mapping Function & Mutations
- Structural comparison: RMSD concepts and alignment-based comparisons.
- Identifying active sites, binding pockets (conceptual) and conserved motifs.
- Mapping variants/mutations onto structures and interpreting potential impacts (carefully).
- Communicating uncertainty: distinguishing hypotheses from validated conclusions.
Module 8: Best Practices, Reproducible Reporting & Responsible Use
- Keeping a modeling log: inputs, templates, parameters, versions, scores.
- Figures and reporting: what to show in a paper (confidence, validation plots, key residues).
- Reproducibility: saving sequences, alignments, models, and scripts.
- Ethics and scope: avoiding clinical claims and overinterpretation from predicted models.
Final Project
- Select a protein sequence (provided or your own) and define a research question.
- Predict structure(s) using one or more approaches and assess confidence.
