Regulatory Mechanisms of Meiosis in Fission Yeast

裂殖酵母减数分裂的调控机制

基本信息

项目摘要

We investigated the regulatory mechanisms of meiosis in fission yeast. Certain mRNAs required for meiosis are transcribed but undergo degradation called "selective elimination" in vegetatively growing cells. We analyzed this mechanism and identified a number of molecules involved. A pivotal factor Mmi1 protein recognized and bound to specific hexanucleotide motifs on the target mRNAs. meiRNA, which inactivates Mmi1 to promote meiosis, carried numerous copies of the hexanucleotide motifs and lured Mmi1. Meanwhile, we found that phosphorylation of Ser-2 residues on the C-terminal domain (CTD) of RNA polymerase II was essential to transcribe a specific gene required for the initiation of meiosis, and that the stress-responsive MAP kinase pathway was involved in this regulation.
我们研究了裂变酵母中减数分裂的调节机制。在植被生长的细胞中,转录了减数分裂所需的某些mRNA,但被称为“选择性消除”。我们分析了这种机制,并确定了许多涉及的分子。识别并与靶mRNA上的特定六核苷酸基序结合的关键因子MMI1蛋白。 Meirna灭活MMI1以促进减数分裂,它携带了许多六核苷酸基序的副本并吸引了MMI1。同时,我们发现RNA聚合酶II的C末端结构域(CTD)在RNA聚合酶II的C末端磷酸化对于转录减数分裂所需的特定基因至关重要,而应力反应性MAP激酶途径与该调节有关。
