在人血液中发现了两种不同的胰岛素样生长因子(IGF)结合蛋白,一种是依赖生长激素合成的高分子质量蛋白,另一种是依赖生长激素合成的低分子质量蛋白。人羊水中含有丰富的igf结合蛋白。它的氨基酸序列现在已经通过对蛋白质及其蛋白水解片段的直接分析确定。同时,通过免疫筛选,从人肝癌细胞系中分离出部分cDNA克隆。成熟蛋白由234个氨基酸组成,由长度约为1700个核苷酸的mRNA编码。该蛋白的初级结构显示在n端和c端簇中有18个Cys残基,以及一个Arg-Gly-Asp肽序列,与整合素家族受体结合的细胞外蛋白共同。在Ile/Met-228位点检测到蛋白序列多态性,提示可能存在等位基因变异。3'-未翻译mRNA序列具有高的a + T含量,并显示5个ATTTA序列拷贝,已被证明参与调节某些编码生长调节蛋白的mRNA的稳定性。
Two different insulin-like growth-factor (IGF)-binding proteins have been found in human blood, one of high molecular mass and dependent on growth hormone for synthesis, the other of low molecular mass and independent of growth hormone. The small IGF-binding protein is abundant in human amniotic fluid. Its amino acid sequence has now been determined by direct analysis of the protein and its proteolytic fragments. Also, by immunoscreening a partial cDNA clone was isolated from a human hepatoma cell line. The mature protein consists of 234 amino acids and is coded for by an mRNA of approximately 1700 nucleotides in length. The primary structure of the protein reveals 18 Cys residues in N-terminal and C-terminal clusters and an Arg-Gly-Asp peptide sequence, common to extracellular proteins binding to receptors of the integrin family. A protein-sequence polymorphism was detected at position Ile/Met-228, indicating possible allelic variation. The 3'-untranslated mRNA sequence has a high A + T content and shows five copies of an ATTTA sequence, which has been shown to be involved in the regulation of the stability of certain mRNAs coding for growth-regulating proteins.
