Babak Javid

Babak Javid is a physician scientist with an interest in tuberculosis, infectious diseases and protein translational fidelity. He did his medical training in the UK, his PhD on antigen processing and presentation with Paul Lehner at Cambridge, and post-doctoral training on mycobacterial genetics with Eric Rubin at Harvard. He joined Tsinghua School of Medicine in October 2011.

Mycobacterial infections are characterized by the need of the host to contain the invading pathogen as well as by the need of the pathogen to escape the host cell in order to infect other cells. An important phase during this interaction pertains to host cell death decision pathway. My project involves looking at this pathway using proteomic tools to get some clues about how mycobacteria can influence the manner in which host cells die.;

In a homogeneous bacterial population (identical in genomic information), the phenotypes of individual cells may vary significantly due to gene expression, protein synthesis and other processes. One reason for this variation may be the rate of errors generated during protein synthesis (mistranslation), which we hypothesise may benefit cell survival when they are challenged by stress or antibiotics. I am designing novel reporters to measure mistranslation at the single cell level. I hope to find what's controlling the heterogeneity of mistranslation in a clonal population and a potential clues for novel drug development.

Based on previous work of the lab, mycobacteria could tolerate high mistranslation rates and this phenotype could help them to adapt to different kinds of environment including some antibiotic such as rifampicin. So there may be some specific elements which control translational fidelity. My project is to find the genetic elements controlling mycobacterial translation fidelity using forward genetic screens.

In mycobacteria tRNAAsn and tRNAGln are generated by a two-step synthesis, involving physiological misacylation to Glu-tRNAGln and Asp-tRNAAsn intermediates which are amidated to the cognate forms by GatCAB. I am focusing on the role of GatCAB in this indirect pathway to identify its potential link to relative mistranslation rate in mycobacteria. I am also interested in mechanisms to manipulate mycobacteria genetically including generation of SNPs via recombineering.

My projects are based on the hypothesis that mistranslation may contribute to mycobacterial adaption to the intracellular environment. One of my projects is to verify the hypothesis by measuring the mycobacterial mistranslation rate before or after infection; the other one is to understand the interactions between the host and mycobacteria during the process of infection.

I am investigating the role of EF-Tu discrimination in mycobacterial mistranslation, which will examine one potential mechanism for mycobacterial mistranslation. The residing dogma states that misacylated tRNAs cannot take part in protein translation due to discrimination by EF-Tu, but this has not been investigated in vivo.
We know that fidelity in translation is associated with two key events: synthesis of correctly charged aminoacyl transfer RNAs (aa-tRNAs) by aminoacyl tRNA synthetases (aaRSs) and accurate selection of aa-tRNAs by the ribosome. However, the precise molecular mechanism of mycobacterial mistranslation is poorly understood. Specifically, it is not known if mistranslation results from errors of ribosomal decoding or misacylation of amino-acylated tRNAs. This is particularly relevant since mycobacteria physiologically misacylate glutamine and asparagine tRNAs before modifying them to the correct form by the action of the enzyme GatCAB.

The previous work of the lab indicates that mistranslation may help mycobacteria survive in some antibiotic environments such as rifampicin. This finding leads us to further think the mechanism and effects of mistranslation in eukaryote. So, I choose yeast as my research material, trying to find the genetic elements controlling translation fidelity and find out what effects mistranslation may have on eukaryote.
