Protein synthesis: mRna surveillance by the ribosome
Rachel Green (Johns Hopkins U., HHMI) 2: Protein synthesis: mRna surveillance by the ribosome
Talk Overview:
In her first talk, Green provides a detailed look at protein synthesis, or translation. Translation is the process by which nucleotides, the “language” of Dna and Rna, are translated into amino acids, the “language” of proteins. Green begins by describing the components needed for translation; mRna, tRna, ribosomes, and the initiation, elongation, and termination factors. She then explains the roles of these players in ensuring accuracy during the initiation, elongation, termination and recycling steps of the translation process. By comparing translation in bacteria and eukaryotes, Green explains that it is possible to determine which components and steps are highly conserved and predate the divergence of different kingdoms on the tree of life, and which are more recent adaptations.
Green’s second talk focuses on work from her lab investigating how ribosomes detect defective mRnas and trigger events leading to the degradation of the bad Rna and the incompletely translated protein product and to the recycling of the ribosome components. Working in yeast and using a number of biochemical and genetic techniques, Green’s lab showed that the protein Dom34 is critical for facilitating ribosome release from the short mRnas that result from mRna cleavage. Experiments showed that Dom34-mediated rescue of ribosomes from short mRnas is an essential process for cell survival in higher eukaryotes.
Speaker Biography:
Rachel Green received her BS in chemistry from the University of Michigan. She then moved to Harvard to pursue her PhD in the lab of Jack Szostak where she worked on designing catalytic Rna molecules and investigating their implications for the evolution of life. As a post-doctoral fellow at the University of California, Santa Cruz, Green began to study how the ribosome translates mRna to protein with such accuracy.
Currently, Green is a Professor of Molecular Biology and Genetics at the Johns Hopkins School of Medicine and an Investigator of the Howard Hughes Medical Institute. Research in her lab continues to focus on the ribosome and factors involved in the fidelity of eukaryotic and prokaryotic translation.
Green is the recipient of a Johns Hopkins University School of Medicine Graduate Teaching Award as well as the recipient for numerous awards for her research. She was elected to the national Academy of Sciences in 2012.
Dna聚合酶链式反应
What are Dna polymerases? Dna polymerases are enzymes responsible for assembling nucleotides to create new Dna molecules. These Dna polymerases are indispensable to cell divisions as they duplicate the genetic information that would be passed to the next generation of daughter cells. Throughout the years, scientists have utilized different variants of Dna polymerases for different applications.
从实验到分析——深度解析基于二代测序的LncRna研究及应用
非编码Rna起初被认为是基因组转录的“垃圾”,而近年来,多个高水平的杂志以封面形式报道长链非编码Rna(long non-coding Rna,LncRna)的重要性,由此LncRnas引起了人们广泛的关注,已成为各研究领域的一颗新星。
本次讲座主要将从以下几个方面展开:
①LncRna的方案设计及研究思路
②LncRna的实验及分析流程
③LncRna的案例解析
④LncRna+mRna+miRna联合分析方案解析
⑤一类特殊的ncRna——circular Rna
