我们先前不仅显示了编码小鼠PG-M核心蛋白的不同大小的多个RNA转录物的存在,而且还显示了它们的组织依赖性表达。发现多种形式的主要原因是由于两种不同硫酸软骨素附着结构域(α和β)的替代使用。在这项研究中,基因组DNA分析表明,这些结构域是由两个大的外显子,外显子VII(2880碱基对)和外显子VIII(5229碱基对)编码。这两个外显子的剪接位点与无移码的选择性剪接的发生一致。此外,小鼠PG-M基因被证明有四个不同的聚腺苷酸化信号和三个候选的转录起始位点以及。这些基因组结构变异可能有助于PG-M转录本的多样性。北方杂交分析表明,至少有三个不同的转录本产生的不同用途的独特的多聚腺苷酸化信号。
We previously showed not only the presence of multiple RNA transcripts of different sizes encoding the core protein of mouse PG-M, but also their tissue-dependent expression. Major causes for the multiple forms were found to be due to alternative usage of the two different chondroitin sulfate attachment domains (α and β). In this study, genomic DNA analysis has revealed that these domains are encoded by two large exons, exon VII (2880 base pairs) and exon VIII (5229 base pairs). The splice sites of these two exons were consistent with the occurrence of alternative splicing without frameshift. Furthermore, the mouse PG-M gene was shown to have four distinct polyadenylation signals and three candidates for the transcription initiation site as well. These genomic structural variations may contribute to the multiplicity of PG-M transcripts. Northern hybridization analysis showed that at least three different transcripts were generated by different usage of the distinct polyadenylation signals.
