Nuclear pore complexes (NPCs) are channels composed of multiple proteins that ferry molecules in and out of the nucleus, regulating many critical cellular functions, such as gene expression, chromatin ...
UNSW medical researcher Dr. David Jacques and his team have discovered how the human immunodeficiency virus (HIV) breaches the cell nucleus to establish infection, a finding that has implications ...
The nuclear pore complex (NPC) is an essential, highly dynamic macromolecular assembly embedded in the nuclear envelope that orchestrates the precise exchange of proteins, RNA and other macromolecules ...
Because viruses have to hijack someone else’s cell to replicate, they’ve gotten very good at it—inventing all sorts of tricks. A new study from two University of Chicago scientists has revealed how ...
Nuclear pore complexes are more dynamic than previously thought, reshaping our understanding of a vital transport process in cells. An international study led by the University of Basel (Switzerland) ...
As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to lock it down like Fort Knox. Instead, large groupings of more than 1,000 ...
If the cell nucleus is like a bank for DNA, nuclear pores are the security doors around its perimeter. Yet more security doors aren't necessarily better: some cancer cells contain a dramatic excess of ...
A model of transport through the nuclear pore complex. The blue spheres represent macromolecules that do not interact with the selectively permeable barrier of the complex, while the red spheres ...
Proteins are most well-known for their intricate structures. The α-helices and β-sheets that form from interactions between sidechains create distinct shapes that, along with the specific amino acid ...
Adenoviruses have a linchpin protein that stabilizes their DNA until it reaches the infected cell's nucleus. The protein then detaches from the viral genome, and the virus uncoats. Only then are the ...
