Translation initiation is a highly regulated, multi-step process that is critical for efficient and accurate protein synthesis. In bacteria, initiation begins when mRNA, initiation factors, and a...

New preprint on collaboration with Yu and Luo labs. There is a bioorthogonal click screen of Hmt1 substrates suggesting lots of factors in translational control are methylated by Hmt1 in yeast, and evidence that Arginine methylation of eIF1A NTT loosens start codon fidelity.

WNY is a fun place to live for people with or without families. My favorite life things are the hiking and fun winter activities, amazing summer and fall, spring wildflowers, festivals, breweries and distilleries, without traffic and high housing costs of where I lived before.

We’re now looking for two people for two different projects, one looking at translation initiation mechanisms and regulation under stress and another looking at translational control that affects metastasis in breast cancer models

We’re hiring at the postdoc level. If you know of people looking for a postdoc or research scientist position in molecular mechanisms of translational control, send them my way. https://t.co/fbuw7Nkb8A

Check out our latest: Using smFRET, we determine an entirely new mechanism for mRNA activation. As part of this work, we assign novel functions for each of the eIF4F components, including a 'hopping' activity of eIF4G and a 'strippase' activity of eIF4A. 🔬 https://t.co/eFWXMQqsmT

Using real-time imaging to watch human ribosomes decode mRNA, scientists find that the process is 10x slower in humans than in bacteria. Proofreading is the rate-limiting step. @TheBlanchardLab @ERundlet

Cool RNA biochemistry. Drugs that inhibit 2′-O-methylation of the first nucleotide of mRNAs prevent cap snatching by influenza and inhibit viral replication.

Inhibition of a host methyltransferase interferes with binding of host cap RNAs to viral polymerase and inhibits influenza virus replication.

Our paper is now online 🙌 https://t.co/3yrwBpXG80 5'UTR purine-rich motifs deliver eIF4A1 unwinding activity site-specifically into repressive RNA structures of mRNAs encoding proliferative signatures. Well done all @CRUK_BI @CR_Horizons @ILikeHelicases @NAR_Open @RNASociety

Abstract. Altered eIF4A1 activity promotes translation of highly structured, eIF4A1-dependent oncogene mRNAs at root of oncogenic translational programmes.

Our paper on dormant egg ribosomes is out now! I couldn't be more grateful to work with @llorenzoorts,@PauliGroup @HaselbachLab and so many others. I learned so much and discovered my passion for #ribosomes
https://t.co/8dITd4pmfz Thank you for your enthusiasm and support!
