Nuclear Pore Complex StructureUnplugged and Dynamic Pores [PDF]
Developmental Cell, 2004 Nuclear pore complexes (NPCs) are large protein assemblies embedded in the nuclear envelope that act as passageways for transport of molecules into and out of the nucleus. Two new studies, one in Nature Cell Biology and one in Science , offer direct evidence that the NPC is a highly dynamic structure.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Structural and Biochemical Studies of the Human DEAD-box Helicase Dbp5 and Nucleoporin Nup214 Involved in mRNA Export [PDF]
, 2009 The hallmark of eukaryotic evolution was the development of the nucleus in cells. This compartmentalization requires the nucleocytoplasmic transport of thousands of molecules. The gate into and out of the nucleus is the nuclear pore complex (NPC). One of

Nuclear Pore Proteins in Regulation of Chromatin State
Cells, 2019 Nuclear pore complexes (NPCs) are canonically known to regulate nucleocytoplasmic transport. However, research efforts over the last decade have demonstrated that NPCs and their constituent nucleoporins (Nups) also interact with the genome and perform ...

Nuclear envelope: membrane bending for pore formation?
, 2009 Membrane-shaping proteins known as reticulons help to sculpt the endoplasmic reticulum; recent findings indicate that they also play a role in the formation of nuclear-pore-complex-associated pores in the nuclear ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Herpes simplex virus ICP27 protein directly interacts with the nuclear pore complex through NUP62, inhibiting host nucleocytoplasmic transport pathways [PDF]
, 2012 The herpes simplex virus ICP27 protein is important for the expression and nuclear export of viral mRNAs. Although several binding sites have been mapped along the ICP27 sequence for various RNA and protein partners including the transport receptor TAP ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
