UniProt features at this position:

(none catalogued)

Position 365 sits in the C-terminal lumenal domain (residues 653–869), wolframin's largest soluble region. This domain projects into the ER lumen and is implicated in calcium handling, ER stress sensing, and protein–protein interactions with ATF6 and Na+/K+ ATPase β1. The wild-type residue is large aromatic hydrophobic (phenylalanine); the mutant is small polar (serine — hydroxyl). The chemistry shift implies altered local packing, hydrogen-bonding, and/or electrostatics at this site.

Final Schema Categorization

Category 3/4 — Most Druggable

<strong>Category 3/4 — Most Druggable</strong><br/><br/>|ΔΔG|=0.93 < 2 kcal/mol (fold intact) + AlphaMissense 0.977 confirms functional impact. Specific local contacts disrupted — priority for docking and pharmacological chaperone screening.

Why this card matters. Wolframin's fold survives this substitution (|ΔΔG|=0.93 kcal/mol). The pathogenic signal is real — AlphaMissense places it at 0.977. Protein still folds, but a specific local site is broken. Pharmacological chaperones and small-molecule binders are the rational therapeutic vector.
