Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title methanol-solvated salt, C14H19Cl3N5O2+·Cl−·CH3OH, the triazine molecule is protonated at one of the triazine N atoms. In the crystal, the triazine cations are linked through a pair of N—H...N hydrogen bonds, with graph-set R22(8), forming an

Cilia regeneration requires an RNA splicing factor from the ciliary base
Cell Regeneration, 2022 Cilia are microtubule-based organelles projected from most eukaryotic cell surfaces performing cell motility and signaling. Several previously recognized non-ciliary proteins play crucial roles in cilium formation and function.

Protein structure paintings [PDF]
Proceedings of the National Academy of Sciences, 2014 When artist Steve Miller met Nobel Laureate Rod MacKinnon at Brookhaven National Laboratory in New York, MacKinnon was investigating protein structures: specifically, how potassium ions move across cell membranes. Miller became fascinated with the visual tools MacKinnon used to grapple with the problem: 3D computer models of proteins, graphical ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Structure optimization in an off-lattice protein model
, 2003 We study an off-lattice protein toy model with two species of monomers interacting through modified Lennard-Jones interactions. Low energy configurations are optimized using the pruned-enriched-Rosenbluth method (PERM), hitherto employed to native state ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

CABS-flex 2.0: a web server for fast simulations of flexibility of protein structures
, 2018 Classical simulations of protein flexibility remain computationally expensive, especially for large proteins. A few years ago, we developed a fast method for predicting protein structure fluctuations that uses a single protein model as the input.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
