一般描述

胶原α-1(I)链(UniProt P02452;也称为α-1 I型胶原)由人的COL1A1基因(基因ID 1277)编码。胶原蛋白是细胞外基质(ECM)的主要成分,并形成肌腱,韧带和骨骼的原纤维。I型胶原由两条αI链和一条α2链组成。α-1 I型胶原最初以1464个氨基酸的前体形式生产,具有信号肽序列(a.a.1-22)和两个前肽序列(a.a.23-161和a.a.1219 –1464),去除该序列会产生成熟的α-1(I)链。成熟的α-1(I)链主要由一个大的三螺旋区(a.a.179-1192),三螺旋区夹在两个非螺旋片段之间,称为N-末端端肽(a.a.162-178;编号基于前体形式)和C末端端肽(a.a.1193-1218;编号基于前体形式)。胶原可以通过酶法或非酶法从组织中提取。使用蛋白水解酶胃蛋白酶提取的胶原对应于大的三螺旋区域,称为端胶原,因为N末端和C末端端肽均已被胃蛋白酶裂解。另一方面,通过非酶方法(例如通过酸提取)获得的胶原制剂在两端具有完整的端肽。

特异性

基于高序列同源性,预计可与多种物种(包括哺乳动物、鸟类、鱼类和两栖动物)发生反应。
针对源自C末端前肽(而非N末端前肽)区域的序列,产生了目录号ABT257 I型抗前胶原A1/COL1A1。该多克隆抗体可检测前体和前原胶原α-1(I)链,但不能检测成熟胶原α-1(I)链。

免疫原

对应于源自人I型前胶原,A1/COL1A1 C末端前肽区的序列的线性肽。
表位:C末端前肽区域

应用

抗I型前胶原抗体是针对I型前胶原的抗体,用于蛋白质印迹、流式细胞仪、免疫组化。
