1. Protein Identity and Related Structures Protein Identity & Related Structures

No usable UniProt protein identity is available for this entry.

The relationship tables retain this entry's assembly and composition data, but cross-PDB links for the same protein cannot be established reliably without a unified protein identity.

Assembly Composition of the Current Entry

Assembly	Physical composition	Protein state	蛋白 / DNA / RNA / 其他Polymer	Data consistency
1	Protein heterocomplex	Heteromer	28 / 0 / 0 / 0	Consistent with protein count

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.
