UniProt P99999 · 105 residues

AlphaFold's confidence, residue by residue: 103 very high (90 and above) · 2 confident (70 to 90) · 0 low (50 to 70) · 0 very low (below 50).

Ask this protein

• What does it look like? 105 residues: 98% very high confidence, 0% very low.
• Where could a drug bind?
• Can I print it and fill it in by hand?

The next questions its numbers invite

• Does a confident model mean it never moves? 103 of its 105 residues are at pLDDT 90 or above.
• What does a single-chain model leave out? Every AlphaFold DB entry is one chain on its own: no partners, metals or cofactors.

These follow-ups come from a short hand-written table that reads only the numbers above: many residues below 50 invites the disorder games; most at 90 or above invites the one about movement. They are questions to try, not findings about this protein.
