Protein Atlas · Discovery EngineIndia HLA × autoantigen × mimicryResearch-grade hypothesis surface
Autoimmunity as a protein-recognition problem.
Every step of autoimmune disease is one protein recognising another. An HLA protein presents a self-peptide. A T-cell receptor reads it. An autoantibody attacks. The frontier of open protein models (ESM-2 · MHCflurry · Evo 2) is pointed at the disease mechanism, not a proxy. For Indians the HLA proteins differ, so the presented self-peptidome differs, so the autoantigen repertoire differs — and almost no one has computed this.
What this engine returns: ranked autoantigen candidates (with PTM annotations), India-pathogen molecular mimicry hypotheses, and the open research wedges your patient phenotype maps to. Computation collapses discovery from years to weeks; it does not replace validation. Every output is a hypothesis requiring wet-lab confirmation.
HYPOTHESIS-ONLY · NOT A CLINICAL DIAGNOSTIC
Real-time peptide-MHC scoring (MHCflurry / NetMHCpan / ESMCBA) is a Phase 1 build per autoimmune_protein_deep_research.md §10. Today this endpoint surfaces the curated knowledge layer + the open research wedges. AlphaFold3 is firewalled to the research lane per §9 license discipline. The shipped product is commercial-clean.
The 5-layer protein-recognition stack
How the engine is architected. Commercial-clean models in the shipped product (ESM-2 MIT, MHCflurry open, Evo 2 open); AlphaFold3 firewalled to the research lane for paper-grade structural confirmation per §9 license discipline.
Indian HLA proteins differ at MHC pockets — anchor preferences differ.

Peptide-MHC presentation
Workhorse layer. Pan-allele models work on Indian HLA without Indian-specific training data.
MHCflurry 2.0 (open) · NetMHCpan (verify) · ESMCBA (2025)
Citrullination changes binding. PetriDish models the MODIFIED peptide, not just the genome.
BepiPred / DiscoTope (open) · Custom PTM layer (proprietary)
Frontier. Honest hard limit. Hypothesis generation only — no clinical claim.
NetTCR / pMTnet / EPIC-TRACE (verify) · AF3 structural (research lane)
India angle. Dengue · CHIKV · Strep · TB peptides cross-reactive with Indian HLA-restricted self.
IEDB + NetMHC pipeline · AF3 docking (research lane)
Research-grade hypothesis surface. Computation collapses discovery; it does not replace validation. Decision support positioning, not a medical device.
