为了鉴定可能参与造血控制的具有表皮生长因子(EGF)结构域的细胞外蛋白,我们对小鼠骨髓基质细胞系 MS-5 进行了简并逆转录酶介导的 PCR,并分离了编码与 Notch 蛋白相关的 EGF 样结构域的新部分 cDNA。全长cDNA的克隆和测序表明它编码一种新的胞外多结构域蛋白,我们将其命名为polydom。这种 387 kDa 的嵌合蛋白包含一个信号肽,随后是八个不同蛋白质结构域的新关联,包括一个五聚蛋白结构域和一个冯维勒布兰德因子 A 型结构域、十个 EGF 结构域和 34 个补体控制蛋白模块。人polydom mRNA在胎盘中强烈表达,其在其他组织中的表达较弱或检测不到。编码蛋白的特殊多结构域结构表明在细胞粘附和/或免疫系统中具有重要的生物学作用。
To identify extracellular proteins with epidermal growth factor (EGF) domains that are potentially involved in the control of haemopoiesis, we performed degenerate reverse-transcriptase-mediated PCR on the murine bone-marrow stromal cell line MS-5 and isolated a new partial cDNA encoding EGF-like domains related to those in the Notch proteins. Cloning and sequencing of the full-length cDNA showed that it encoded a new extracellular multi-domain protein that we named polydom. This 387 kDa mosaic protein contained a signal peptide followed by a new association of eight different protein domains, including a pentraxin domain and a von Willebrand factor type A domain, ten EGF domains, and 34 complement control protein modules. The human polydom mRNA is strongly expressed in placenta, its expression in the other tissues being weak or undetectable. The particular multidomain structure of the encoded protein suggests an important biological role in cellular adhesion and/or in the immune system.
