1. 蛋白身份与相关结构 Protein Identity & Related Structures

当前条目没有可用的 UniProt 蛋白身份。

七张关系表仍保留该条目的 assembly 与组成信息，但缺少统一蛋白身份时，不能可靠建立跨 PDB 的同蛋白链接。

当前条目的 assembly 组成

Assembly	物理组成	蛋白状态	蛋白 / DNA / RNA / 其他聚合物	数据核对
1	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
2	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
3	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
4	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
5	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
6	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
7	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
8	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致
9	蛋白单体	单体	1 / 0 / 0 / 0	与蛋白数一致

页面优先展示蛋白身份、当前 assembly、共同组分、聚集状态和跨 PDB 结构链接。链映射与序列区间收在“数据证据”中；数据库内部编号、导入时间和 assembly 操作表达式仅用于维护，因此不在读者页面展示。
