FAQPage Schema

How do I validate protein designs using AlphaFold2 predictions?▼

You can validate protein designs by running an AlphaFold2 prediction pipeline on your design FASTA to generate ranked models and assess structural integrity using confidence metrics like pLDDT, pTM, and ipTM.

What do pLDDT, pTM, and ipTM metrics indicate in protein structure prediction?▼

These metrics assess predicted structural confidence: pLDDT measures local chain accuracy, while pTM and ipTM evaluate global complex and interface integrity to guide protein design decisions.

Can I validate multi-chain complexes and binder-target interfaces with AlphaFold?▼

Yes, AlphaFold-based validation supports multi-chain contexts and binder-target validations, allowing you to assess binding interfaces and structural integrity across complex protein assemblies.

Do I need a GPU and Python 3.8+ to run AlphaFold2 structure predictions?▼

Yes, you need Python 3.8+ and a GPU-enabled environment, using either ColabFold or local AlphaFold2 installations, along with access to requisite databases for deterministic runs.

Why should I check self-consistency across multiple AlphaFold models?▼

Comparing self-consistency across multiple AlphaFold models helps identify robust protein designs and flags structural inconsistencies, ensuring the predicted folding is reliable and stable.

What are the limitations of using AlphaFold for protein design validation?▼

AlphaFold validation requires GPU-enabled environments and database access for deterministic runs, and relies on confidence metrics like pLDDT and ipTM which may not capture all dynamic binding behaviors.
