SH2db

To organize these protein structures efficiently, we introduce (i) a generic residue numbering scheme to enhance the comparability of different SH2 domains, (ii) a structure-based multiple sequence alignment of all 120 human wild-type SH2 domain sequences and their PDB and AlphaFold structures. The aligned sequences and structures can be searched, browsed and downloaded from the online interface of SH2db (http://sh2db.ttk.hu), with functions to conveniently prepare multiple structures into a Pymol session, and to export simple charts on the contents of the database.

为高效组织此类蛋白质结构，我们提出两项方案：（i）一套通用残基编号体系，用以提升不同SH2结构域（SH2 domain）之间的可比性；（ii）针对人类全部120条野生型SH2结构域序列及其PDB、AlphaFold结构所构建的基于结构的多重序列比对结果。上述经比对的序列与结构可通过SH2db的在线界面（http://sh2db.ttk.hu）进行检索、浏览与下载，该平台还配备便捷功能，可将多个结构整合为PyMOL会话文件，并导出数据库内容相关的简易图表。

背景概述

SH2db是一个专门针对SH2结构域的信息系统，SH2结构域作为关键的蛋白质相互作用模块，在药物发现中具有重要价值。该数据集提供了预对齐的SH2结构域序列和结构，支持用户浏览、搜索和下载相关数据，并方便地准备Pymol会话。
