UniProt P02768 · 609 residues

AlphaFold's confidence, residue by residue: 536 very high (90 and above) · 47 confident (70 to 90) · 1 low (50 to 70) · 25 very low (below 50).

Ask this protein

• What does it look like? 609 residues: 88% very high confidence, 4% 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? 536 of its 609 residues are at pLDDT 90 or above.
• Could it be more than one piece, and how sure are they of each other? It is 609 residues long; long chains are often built from domains.
• 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.
