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 | 蛋白同源多聚体 | 同源多聚体 | 4 / 0 / 0 / 0 | 与蛋白数一致 |
| 2 | 蛋白同源多聚体 | 同源多聚体 | 2 / 0 / 0 / 0 | 与蛋白数一致 |
| 3 | 蛋白同源多聚体 | 同源多聚体 | 2 / 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。
