LSU Health New Orleans study discovers source of Zika neurodevelopmental defects
(Louisiana State University Health Sciences Center) A study led by Edward Wojcik, PhD, Associate Professor of Biochemistry& Molecular Biology at LSU Health New Orleans School of Medicine, identified how microcephaly (abnormally small heads) and blindness may develop in Zika-infected fetuses, as well as a new way to potentially prevent these neurodevelopmental defects.

Committee with no domain expertise approved indigenously manufactured Covaxin: Health experts
“The committee is Delhi centric and dominated by disciplines not connected to vaccines and clinical research. Like in the US such important committees should be multidisciplinary with virologist, persons having a background in cellular and molecular biology, biochemistry, public health and experie nce of conducting clinical research,” former health secretary Sujatha Rao said.

Disrupted biochemical pathway in the brain linked to bipolar disorder
(University of Wisconsin-Madison) In new research, scientists at the University of Wisconsin-Madison have found for the first time that disruptions to a particular protein called Akt can lead to the brain changes characteristic of bipolar disorder. The results offer a foundation for research into treating the often-overlooked cognitive impairments of bipolar disorder, such as memory loss, and add to a growing understanding of how the biochemistry of the brain affects health and disease.

Designed proteins assemble antibodies into modular nanocages
Multivalent display of receptor-engaging antibodies or ligands can enhance their activity. Instead of achieving multivalency by attachment to preexisting scaffolds, here we unite form and function by the computational design of nanocages in which one structural component is an antibody or Fc-ligand fusion and the second is a designed antibody-binding homo-oligomer that drives nanocage assembly. Structures of eight nanocages determined by electron microscopy spanning dihedral, tetrahedral, octahedral, and icosahedral architectures with 2, 6, 12, and 30 antibodies per nanocage, respectively, closely match the corresponding c...

Structure of the human Mediator-bound transcription preinitiation complex
Eukaryotic transcription requires the assembly of a multisubunit preinitiation complex (PIC) composed of RNA polymerase II (Pol II) and the general transcription factors. The coactivator Mediator is recruited by transcription factors, facilitates the assembly of the PIC, and stimulates phosphorylation of the Pol II C-terminal domain (CTD) by the TFIIH subunit CDK7. Here, we present the cryo–electron microscopy structure of the human Mediator-bound PIC at a resolution below 4 angstroms. Transcription factor binding sites within Mediator are primarily flexibly tethered to the tail module. CDK7 is stabilized by multiple...

The molecular assembly of the marsupial {gamma}{mu} T cell receptor defines a third T cell lineage
We describe a population of μTCRs found exclusively in non-eutherian mammals that consist of a two-domain (V-C) -chain paired to a three-domain (Vμ-Vμj-Cμ) μ-chain. μTCRs were characterized by restricted diversity in the V and Vμj domains and a highly diverse unpaired Vμ domain. Crystal structures of two distinct μTCRs revealed the structural basis of the association of the μTCR heterodimer. The Vμ domain shared the characteristics of a single-domain antibody within which the hypervariable CDR3μ loop suggests a major antigen recognition determinant. We define here the molecular basis und...
