一般說明

COL3A1 基因位于人染色体 2q32.2,编码III型胶原蛋白的 α1链。III 型胶原蛋白是一种细胞外基质,包含一个由三条α1链组成的长三螺旋结构域。III 型胶原蛋白是中空性器官(如大血管、子宫和肠)的主要结构成分。人III型胶原纯化方法如下:以温和的胃蛋白酶消化后,对人胎盘的乙酸提取物进行连续盐沉淀、乙醇沉淀和DEAE色谱。 产品来源:人胎盘,HbsAG、HCV和HIV 1 & 2抗体为阴性。

應用

人III 型胶原蛋白已用于:
  • 作为微阵列分析中的细胞外基质(ECM)蛋白,用于包被硝化纤维膜载玻片进行探测和检测
  • 包被微流控迁移设备并研究细胞外基质(ECM)对细胞迁移的应用
  • 作为PRESTO-Tango 实验和GTP-Rho 下拉实验(pull-down assay)中的阳性对照,用于评估其对细胞信号传导和相互作用的影响。

生化/生理作用

胶原III最初以原胶原的形式产生,原胶原是由形成三链绳索状分子的三个pro-alpha1(III)链组成的蛋白。合成后,前胶原分子被细胞修饰。III型原胶原分子从细胞中释放出来,并通过酶处理,该酶将分子的任一端剪掉小片段以形成成熟的胶原。成熟的胶原分子组装成原纤维。分子之间的交联产生非常稳定的原纤维,有助于胶原组织增强功能
