State in the Current Structure

Assembly	Oligomeric State	Construct	Mutations and Modifications	Ligands, Ions and Associated Components	Method and Experimental Conditions	Structure Quality
1	Protein homooligomer Homooligomer Protein × 2 PDB declaration: dimeric（2） Consistent with protein copy count	Chain A； UniProt 2–123	Fragment：N-TERMINAL DOMAIN	No other associated polymer	X-RAY DIFFRACTION mmCIF provides none of the parsed experimental conditions	Resolution 1.45 Å R-free 0.216

Other States of the Same Protein in the Database

Each row is a biological assembly of the same UniProt protein in another PDB entry. The “Difference from current entry” column identifies evidence-level differences; no tag means the currently parsed fields agree.

No other PDB entry for the same UniProt protein was found.

The page prioritizes protein identity, the current assembly, associated components, oligomeric state and cross-PDB links. Chain mapping and sequence ranges are retained as data evidence. Internal IDs, import timestamps and assembly operation expressions are maintenance fields and are not shown here.
