UniProt P09848 · 1927 residues

AlphaFold's confidence, residue by residue: 1242 very high (90 and above) · 420 confident (70 to 90) · 141 low (50 to 70) · 124 very low (below 50).

Ask this protein

• What does it look like? 1927 residues: 64% very high confidence, 6% very low.
• Where could a drug bind?
• Can I print it and fill it in by hand?

The next questions its numbers invite

• Could it be more than one piece, and how sure are they of each other? It is 1927 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.
