一般描述

纤连蛋白由位于C末端的两个亚基通过二硫键连接而成。在细胞外基质原纤维中,纤连蛋白进一步被二硫键合成高分子量聚合物。不同组织和物种中的纤连蛋白亚基大小在约235至270 kD之间变化。每个亚基由三种类型的重复模块组成:I、II和III。I型重复有12个,长约45个氨基酸,分为三组,两个相邻的II型重复每个有60个氨基酸,而III型重复则有15-17个,每个长约90个氨基酸。I型和II型各自包含两个二硫键,而III型不含二硫键。在III型重复的每个亚基上含有两个游离的巯基。

最近一种新的区域,III1型重复从人胎盘cDNA中被克隆得到,据报道可参与到基质的形成。在一项利用抗体对基质组装所需的纤连蛋白结构域进行分析的实验中,在纤连蛋白的III1型和I型模块上发现了可通过成纤维细胞抑制标记的血浆纤连蛋白结合和不溶化的表位。这提示III1型和I型在纤连蛋白组装的调节中能够起到作用。来自纤连蛋白前两个III型重复的14 kDa片段能够对纤连蛋白基质组装进行抑制的能力进一步支持了这一发现。4 最近发现,以III1重复的C端三分之二为模型的重组片段III1-C可与纤连蛋白结合并诱导纤连蛋白分子自发性二硫键交联成类似于基质纤丝的多聚体
