JBC Thematic Minireview Series - Prions

May 23, 2014 — Prions are self-replicating protein aggregates and are the primary causative factor in a number of neurological diseases in mammals. The minireviews in this thematic series highlight the recent advances in prion biology and the role these unique proteins play in disease.

JBC News Podcast: α-synuclein, living cells and Parkinson’s disease: JBC’s best Cell Biology article of 2013

JBC Best of 2013 logoMarch 10, 2014 — In the last of our four-part podcast series on the best articles of 2013 in the The Journal of Biological Chemistry, we hear about the debate surrounding α-synuclein, which plays a critical role in Parkinson’s disease. Is it an unfolded monomer? Is it a helically-folded tetramer? Paul Fraser, a professor of medical biophysics at the University of Toronto and a JBC associate editor, speaks with Dennis Selkoe, a professor of neurological diseases at Harvard Institutes of Medicine, and Ulf Dettmer, a research fellow in neurology also at Harvard. Selkoe and Dettmer are co-authors of JBC’s best article of 2013 in the Affinity category of Cell Biology. It is titled, “In Vivo Cross-linking Reveals Principally Oligomeric Forms of α-Synuclein and β-Synuclein in Neurons and Non-neural Cells,” and it was published in March. The paper details a new method for cross-linking α-synuclein in living cells that reveals a form consistent with a tetramer. In this conversation, we hear about the prior research leading to this article and what to look forward to as the debate continues.

JBC News Podcast: Key interactions at the HER2-HER3 kinase dimer interface: JBC’s best Signal Transduction article of 2013

JBC Best of 2013 logoMarch 3, 2014 — In Part Three of our series of the best articles of 2013 in the The Journal of Biological Chemistry, we hear a conversation between Alex Toker, a professor in the Department of Pathology at Beth Israel Deaconess Medical Center, and Ron Bose, a medical oncologist and assistant professor in the Division of Biological and Biomedical Sciences at Washington University in St. Louis. Bose is the corresponding author of the paper “Carboxyl Group Footprinting Mass Spectrometry and Molecular Dynamics Identify Key Interactions in the HER2-HER3 Receptor Tyrosine Kinase Interface.” This paper was named the JBC’s Best Article of 2013 in the category of Signal Transduction. The paper provides the first structural characterization of HER2-HER3 heterodimers, which are part of the receptor family that is used in the development of targeted cancer therapies. Here, Bose talks about his more than 10 years of research in the study of tyrosine kinases. He also talks about where the research is going, the development of innovation where mass spectrometry is limited in the study of protein complexes that can’t be crystalized, and the power of interdisciplinary studies for graduate students in science.
