After graduating from Alma College, I began working in the Green lab in June 2000 as a research technician. Bacterial translation has been my main research focus, although I continue to work on a variety of projects in the lab depending on where I'm most useful. Over the years, I have been able to offer technical support to members of the Green lab and have learned many different techniques.

My lab studies ribosome stalling in bacteria. Using genetic selections and in vitro kinetics, we identified and characterized nascent peptides that interfere with their own translation. Through our work on stalling peptides, we became interested in EFP, an elongation factor that suppresses pausing at polyproline motifs, and in the enzymes that modify EFP. In addition, we continue to work on determining the mechanism of how stalled ribosomes are recognized and recycled in bacteria. In 2014 we moved from BYU to Hopkins in order to collaborate more extensively with the Green lab.

I am interested in identifying Dom34:Hbs1-associated extra-ribosomal factors that are involved in no-go decay (NGD) and nonstop decay (NSD) pathways, using immunoprecipitation coupled with liquid chromatography tandem mass spectrometry (LC-MS/MS).

Nearly a third of heritable human disease-causing mutations result in the production of premature translation termination (or nonsense) codons. These premature termination events often result in the degradation of the encoding messenger RNA, preventing the accumulation of potentially harmful truncated proteins, through a process caused nonsense-mediated mRNA decay. Using high-throughput screening and ribosome profiling I am studying the factors that influence stop codon recognition. I am also developing methodologies to rapidly and quantitatively determine small-molecule and protein binding sites on the ribosome.

Current focus of my research is ribosome rescue in both canonical and aberrant translation. Using as well as modifying ribosome profiling, I am pursuing to elucidate the molecular mechanisms and the endogenous regulations of those phenomena. And eating pretzels with bourbon like it's supposed to be.

Translation is a tightly regulated process, yet many of the determinants of this step of gene expression are not understood. One important example is the non-sequence context of messenger RNA (mRNA), which is bound by myriad proteins and decorated with covalent modifications. I am studying how mRNA composition is connected to past events in the mRNA lifecycle (“molecular memory”), and how it subsequently influences translation.

Aberrantly stalled ribosomes on messenger RNAs disrupt translational homeostasis - leading to defects in protein synthesis, and activation of downstream quality control (QC) pathways. Using biochemical, mass-spectrometric and ribosome profiling approaches, I am interested in studying how QC factors spatiotemporally recognize and resolve stalled ribosomes, and how such factors discriminate terminally (“dead end”) stalled ribosomes on defective mRNAs, from transiently paused ribosomes on elongation-limited transcripts.

I am interested in studying different factors that alter the activity of the ribosome.

I’m interested in studying the role of protein synthesis and degradation within the nervous system. Using molecular biology techniques and ribosome profiling, I wish to understand how depolarization can modulate translational control within neurons, as well as characterize rapid protein turnover by the proteasome.

I am interested in further characterizing the mechanisms of eukaryotic translation termination and ribosome recycling through the use of single molecule fluorescence studies. This work is performed using objective-based total internal reflection microscopy.

I am interested in exploring the mechanisms of mRNA decay in mammalian cells, particularly nonsense-mediated decay and deadenylation-dependent decay, by applying high-throughput sequencing methods such as ribosome profiling.

Jamie Wangen, Graduate Student, BCMB

E-Mail: jwangen1 at jhmi dot edu

I am interested in studying the role of translational regulation in the differentiation of hematopoietic cells, particularly of the erythroid lineage, using high-throughput approaches including ribosome profiling. Additionally, I hope to elucidate the particular roles of several ribosomal proteins governing this process.
