<strong>蛋白质交联</strong>（Protein Cross-linking）是指两个或多个蛋白质分子（或同一蛋白质内的不同区域）通过<strong>共价键</strong>连接在一起的过程。这种连接可以是生物体内由<strong>酶</strong>催化的生理过程（如<strong>[[胶原蛋白]]</strong>的成熟稳定、<strong>[[血液凝固]]</strong>），也可以是病理状态下的非酶促反应（如<strong>[[晚期糖基化终末产物]]</strong>导致的组织硬化）。在生物技术领域，化学交联是研究蛋白质三维结构（<strong>[[XL-MS]]</strong>技术）和制备生物材料（如<strong>[[水凝胶]]</strong>）的重要手段。交联限制了多肽链的运动，通常能显著提高蛋白质的稳定性和机械强度，但过度的病理性交联是<strong>[[衰老]]</strong>和纤维化疾病的标志。<br />

<br />
<p style="margin: 15px 0; text-align: justify;"><br />
虽然交联对维持[[细胞外基质]] (ECM) 的强度至关重要，但“过度交联”是许多慢性疾病的根源。<br />

<p style="text-align: justify; color: #334155; font-size: 0.95em;"><br />
在[[肝纤维化]]或[[肺纤维化]]中，LOX 酶过度表达，导致胶原蛋白发生异常紧密的交联。这种“硬化”的 ECM 不仅破坏器官功能，形成的物理屏障还会阻碍药物渗透，并向细胞传递异常的力学信号，促进癌症进展。<br />

<p style="text-align: justify; color: #334155; font-size: 0.95em;"><br />
组织转谷氨酰胺酶 (tTG) 在[[阿尔茨海默病]]和[[亨廷顿舞蹈症]]中活性升高，促进致病蛋白（如 $\beta$-淀粉样蛋白、Huntingtin）发生异常交联，形成难溶性的<strong>[[聚集体]]</strong> (Aggregates)，导致神经元死亡。<br />

<br><strong>原理：</strong> 使用具有特定长度“手臂”的交联剂连接蛋白上距离较近的氨基酸，经酶解和质谱鉴定交联肽段，从而推算出特定残基之间的空间距离约束，辅助构建三维模型。<br />
