Dynamic biological assemblies are strategic and fascinating. We have been exploring molecular recognition by flexible proteins and automatic tracking of changes in complex spectra and medical images. Molecular recognition by proteins with intrinsic disorder A pivotal virus-membrane interaction: Coronaviruses use a region of Spike to merge the viral envelope with the host cell membrane. We continue to be interested in the nature of the lipid interactions with this fusogenic region of Spike. Our articles reported (i) the NMR structure of the fusion peptide in a simple membrane-mimicking environment and (ii) its insertion and distortion of the simple membrane mimic via…

Structural Virology – Host Interactions: The US Food & Drug Administration has now approved two gene replacement therapies: Luxturna™ (2017), a treatment for congenital blindness and Zolgenesma™ (2019) for spinal muscular atrophy (SMA). 1,500 SMA infants have now been treated for this debilitating and fatal genetic disorder. These, and treatments for hemophilia and other diseases, use recombinant rAAV vectors to deliver DNA to afflicted cells. Our structure-function analyses provide a fundamental understanding of the atomic interactions key to cell entry, trafficking, and immune neutralization. These foundations are needed for the engineering of gene therapy vectors that are efficient and specific enough…

The 5′-cap of HIV-1 incompletely spliced mRNAs undergoes hypermethylation by the host trimethylguanosine synthase, resulting in the formation of a trimethylguanosine (TMG) cap. Disrupting this process markedly diminishes HIV infectivity, as the TMG-cap enables the viral RNA to access a specialized translation pathway, ensuring sustained viral protein synthesis when the host’s global translation pathway is dampened in response to the stress induced by pathogen invasion. Our lab focuses on characterizing the RNA structures and molecular interactions necessary for the cap epigenetic modification, using a variety of biophysical techniques including NMR spectroscopy, cryoEM, small angle X-ray scattering and isothermal titration calorimetry.

To investigate the regulation and structure/function of extracellular matrix to tissue specific expression in the pathogenesis of inherited connective tissue disorders. Type I collagen, the predominant structural protein in many tissues provides strength to bone and tendon, integrity to skin, major organs and blood vessels, and support for mineralization of bone and teeth. Abnormalities in type I collagen synthesis and structure are associated with several acquired and inherited connective tissue disorders (osteogenesis imperfecta, Ehlers-Danlos Syndrome and osteoporosis). Investigating the pathogenesis of the different inherited connective tissues disorders and identifying the specific mutations in the type I collagen genes gives us…

My lab is interested in elucidating novel roles of vesicular trafficking in innate immunity and nutrient-deficiency responses. We focus on host clathrin-coated vesicle (CCV) components with novel roles in innate immune signaling, responses to Pseudomonas syringae pathogenic bacteria and iron (Fe) deficiency responses. This research interest has been ignited by my cross-disciplinary postdoctoral training in protein trafficking in plants (Prof. Natasha Raikhel, DOE Plant Research Lab, Michaigan State University, E. Lansing, MI, USA), sterol requirement in yeast endocytosis (Prof. Howard Riezman, Biozentrum, Basel, Switzerland) and syntaxin phosphorylation in plant immune signaling against pathogenic fungi (Cf-9/Avr9) (Prof. Jonathan Jones, Sainsbury Laboratory,…

JA SIGNALING IN WOUND RESPONSE AND INSECT RESISTANCEOur research involves the study of small signaling molecules that cells use to detect extracellular stimuli and to coordinate intra- and intercellular responses. To compensate for their lack of mobility, plants rely heavily on chemical cues to interact with their surroundings. This is one reason why plants are rich sources of pharmaceuticals and provide attractive models for studying chemically mediated cell signaling. We employ highly sensitive mass spectrometry-based methodologies to capture and monitor plants’ chemical signals. The combined approach of mass spectrometry and genomics in the model plant Arabidopsis thaliana has allowed us…
