R14del lethal mutant of phospholamban 22 September 2014

Phospholamban, R14del mutant
Naturally occurring deletion of residue 14 (arginine) in cardiac phospholamban has been linked to the progression of heart disease. To understand the basis of this, Vitaly, Kailey, Gopinath and Kim Ha (Veglia group alumna) undertook biophysical studies of this membrane protein, the results of which have been published in Biochimica et Biophysica Acta. We have established that the regulatory domain of R14del is primarily unfolded, is more dynamic, and has weaker interactions with phospholipid bilayer, the qualities that affect its interaction with other proteins in the heart muscle.

ICMRBS conference 25 August 2014

At the 26-th International Conference on Magnetic Resonance in Biological Systems (ICMRBS), Veglia group will present the following posters:

  • "Phosphorylation at adjacent sites affects phospholamban conformational equilibria to regulate SERCA activity" (Leanna, Vitaly, Gianluigi);

  • "Probing multiple timescale dynamics of a protein kinase A - inhibitor complex" (Geoffrey, Jonggul, Frank, Leanna, Gianluigi);

  • "Direct observation of the three regions in α-synuclein that determine its membrane-bound behaviour" (Giuliana Fusco, Alfonso De Simone, Gopinath, Vitaly, Michele Vendruscolo, Christopher Dobson, Gianluigi);

  • "Allosteric regulation of the sarcoplasmic reticulum Ca2+-ATPase by phospholamban and sarcolipin using solid-state NMR spectroscopy" (talk by Gianluigi).

  • MNMR workshop 03 June 2014

    MNMR workshopMinnesota NMR center is conducting a workshop on the theoretical and practical aspects of nuclear magnetic resonance with an emphasis on protein NMR. The detailed schedule can be found here. Members of the Veglia group will be giving the following lectures:

  • Gianluigi Veglia: Product operator formalism.
  • Tata Gopinath: Pulse sequence engineering.
  • Leanna McDonald: Sequential assignment and protein dynamics.
  • Jonggul Kim: Assignment of methyl groups of large proteins.
  • Vitaly Vostrikov: Structure calculation, analysis and validation using XPLOR-NIH.

    Workshop photos are available on the MNMR Facebook page.


  • α-synuclein interaction with synaptic vesicles models 29 May 2014

    α-synuclein domainsα-synuclein is a 140 residue protein, implicated in the progression of Parkinson's disease. Due to its dynamic nature, it has not been amenable to conventional methods like solution NMR or X-ray crystallography. Veglia group in collaboration with scientists from the University of Cambridge and Imperial College London (UK) employed solid-state magic angle spinning NMR in combination with CEST technique to probe the dynamic regimes of physiologically relevant, non-aggregated form of α-synuclein.
    The results published in Nature Communications allowed us to propose a model for α-synuclein binding to the synaptic vesicles mimicks, reconciling the results of a range of previous studies.

    Leanna McDonald was awarded a three-year Ruth L. Kirschstein Postdoctoral fellowship, supported by the National Institute of Dental and Craniofacial Research.
    Sarah Nelson was a recipient of a Thomas S. Reid Award for Biochemistry, awarded to "a graduate student whose research has applications beyond the academic community".
    Vitaly Vostrikov's poster at the Biomolecular Structure, Dynamics, and Function: Membrane Proteins symposium was picked as a session winner.

    Vitaly also received the Paul D. Boyer-James B. Peter Award, recognizing "a postdoctoral fellow (up to 5 years post-Ph.D.) who has made significant research contributions in any area of biochemistry under the direction of a BMBB faculty member". Previous lab members honored include Nate Traaseth (2008), Larry Masterson (2010), Tata Gopinath (2011) and Raffaello Verardi (2012).
