利用已知RGS蛋白保守区(RGS结构域)对应的简并引物进行PCR扩增,在发育中的爪蟾胚胎中鉴定出6个编码推测RGS蛋白的基因(XRGSI-VI)。RT-PCR分析显示,这些XRGSs的mrna在胚胎发生过程中存在差异表达。在第1期,仅检测到XRGSII mRNA。另一方面,XRGSVI mRNA的表达在14期明显增加,其他3种XRGS (III, IV, V)的表达在25 ~ 40期升高。为了进一步表征XRGS蛋白在爪蟾胚胎中的表达,我们分离了XRGSIII的cDNA克隆。根据确定的核苷酸序列,XRGSIII被认为是哺乳动物RGS5 (XRGS5)的爪蟾同源物。信息素反应晕分析表明,XRGS5的表达抑制了酵母对α -因子的反应,表明XRGS5负调控了爪蟾胚胎发育中g蛋白介导的信号通路。
We identified six genes that encode putative RGS proteins (XRGSI-VI) in developing Xenopus embryos using PCR amplification with degenerate primers corresponding to the conserved region (RGS domain) of known RGS proteins. RT-PCR analysis revealed that mRNAs of these XRGSs are differentially expressed during embryogenesis. At stage 1, only XRGSII mRNA was detected. On the other hand, expression of XRGSVI mRNA increased apparently at stage 14 and expression of three of other XRGS (III, IV, V) elevated between stage 25 and 40. To further characterize XRGS proteins expressed in Xenopus embryos, we isolated a cDNA clone for XRGSIII. Based on determined nucleotide sequence, XRGSIII was considered as a Xenopus homologue of mammalian RGS5 (XRGS5). Genetic analysis using the pheromone response halo assay showed that expression of XRGS5 inhibits yeast response to alpha-factor, suggesting that XRGS5 negatively regulates the G-protein-mediated signaling pathway in developing Xenopus embryos.
