Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families

open access: yesFEBS Open Bio, Volume 16, Issue 2, Page 268-278, February 2026.
IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

open access: yesFEBS Open Bio, Volume 16, Issue 2, Page 382-396, February 2026.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

The Structural Basis of Gene Regulation for DNA Organized as Chromatin

open access: yesCHIMIA, 2001
DNA in the nucleus of eukaryotic cells is organized in chromatin, a nucleoprotein complex containing roughly half DNA and half protein. The nucleosome is the underlying DNA packaging element in chromatin, repeating approximately every 200 base ...

Structure, localization and histone binding properties of nuclear-associated nucleosome assembly protein from Plasmodium falciparum

open access: yesMalaria Journal, 2010
Background Nucleosome assembly proteins (NAPs) are histone chaperones that are crucial for the shuttling and incorporation of histones into nucleosomes.

Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...

Nuclear DNA of plastid origin (NUPTs), neglected driver of genome variation and evolutionary innovation

open access: yesThe Plant Journal, Volume 125, Issue 3, February 2026.
Significance Statement Contrary to expectation, NUPTs do not necessarily have a deleterious or ultimately neutral impact, nor are they necessarily purged from the genome. Instead, they can proliferate and eventually become fixed, generating new and novel genes, gene regions and regulatory elements, thereby significantly contributing to plant nuclear ...

Structural visualization of key steps in nucleosome reorganization by human FACT

open access: yesScientific Reports, 2019
Facilitates chromatin transcription (FACT) is a histone chaperone, which accomplishes both nucleosome assembly and disassembly. Our combined cryo-electron microscopy (EM) and native mass spectrometry (MS) studies revealed novel key steps of nucleosome ...

Cdt1 revisited: complex and tight regulation during the cell cycle and consequences of deregulation in mammalian cells

open access: yesCell Division, 2006
In eukaryotic cells, replication of genomic DNA initiates from multiple replication origins distributed on multiple chromosomes. To ensure that each origin is activated precisely only once during each S phase, a system has evolved which features periodic
