  • 简介:-thymosins,高度保存的肽的一个家庭,起一个重要作用在愈合创伤,angiogenesis,抗菌剂过程和抗病毒的免疫。三新奇-thymosin-repeat蛋白质,命名mjthm4,mjthm3和mjthm2,从抑制用表示顺序标签(EST)从Marsupenaeusjaponicus被克隆减少性的杂交。拥有的mjthm4,mjthm3和mjthm2cDNAs打开编码了166,128和90的读的框架氨基酸残余多肽并且包含了四,三和二-thymosin肌动朊绑定模块分别地。强风分析证明mjthm4,mjthm3和mjthm2与已知的无脊椎的多重复-thymosins分享了高相同。这些蛋白质无所不在地检验纸巾在所有被表示,并且transcriptional层次在肠是最高的。进一步的调查表明mjthm4,mjthm3和mjthm2是显著地起来调整的在WSSV感染以后的6h。而且当mjthm4transcriptional层次没显示变化时,mjthm3和mjthm2层次在病毒抵抗的虾减少了。结果显示mjthm4,mjthm3和mjthm2是新奇多重复-thymosin相当或相同事物,与WSSV感染有一种靠近的关系,并且可能贡献在虾的主人防卫或病毒侵略相互作用的更好的理解。
