从转染的哺乳动物细胞制备来自层粘连蛋白α2链C-末端的四个单独的LG模块(LG 1、LG 2、LG 4和LG 5)和这些模块的组合作为重组产物。这表明LG模块代表自主折叠的蛋白质结构域。成功的生产取决于模块边界的正确对齐,并需要在C-末端添加额外的半胱氨酸的序列校正。LG模块被糖基化,并通过电子显微镜显示具有球形形状,表明正确的折叠。为LG 2中12 bp外显子的剪接提供了证据,尽管这并不损害折叠。在接近LG 3的N-末端的基本序列的C-末端处观察到蛋白水解切割。类似的加工也发生在含有α2链的组织来源的层粘连蛋白-2和-4中。
Four individual LG modules from the C-terminus of the laminin α2 chain (LG1, LG2, LG4 and LG5) and combinations of these modules were prepared as recombinant products from transfected mammalian cells. This demonstrated that LG modules represent autonomously folding protein domains. Successful production depended on proper alignment of module borders and required a sequence correction at the C-terminus which added an extra cysteine. The LG modules were glycosylated and shown by electron microscopy to have a globular shape, indicating proper folding. Evidence is provided for the splicing of a 12 bp exon in LG2, although this did not impair folding. Proteolytic cleavage at the C-terminus of a basic sequence was observed close to the N-terminus of LG3. A similar processing also occurs in tissue-derived laminin-2 and -4 which contain the α2 chain.
