HOCOMOCO: towards a complete collection of transcription factor binding models for human and mouse via large-scale ChIP-Seq analysis

open access: yesNucleic Acids Res., 2017
We present a major update of the HOCOMOCO collection that consists of patterns describing DNA binding specificities for human and mouse transcription factors.

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

The evolution of complex gene regulation by low specificity binding sites

open access: yes, 2012
Transcription factor binding sites vary in their specificity, both within and between species. Binding specificity has a strong impact on the evolution of gene expression, because it determines how easily regulatory interactions are gained and lost ...

Dogon pronominal systems their nature and evolution

open access: yesStudies in African Linguistics, 1994
The Dogon language family has received little attention in the linguistics literature to date. In this paper we examine the binding properties of the pronominal systems of three Dogon languages, Donno S:>, T:>r:> S:>, and Togo Ka.

Topological fingerprints reveal protein-ligand binding mechanism [PDF]

open access: yesarXiv, 2017
Protein-ligand binding is a fundamental biological process that is paramount to many other biological processes, such as signal transduction, metabolic pathways, enzyme construction, cell secretion, gene expression, etc. Accurate prediction of protein-ligand binding affinities is vital to rational drug design and the understanding of protein-ligand ...

Binding Affinity via Docking: Fact and Fiction

open access: yesMolecules, 2018
In 1982, Kuntz et al. published an article with the title “A Geometric Approach to Macromolecule-Ligand Interactions”, where they described a method “to explore geometrically feasible alignment of ligands and receptors of known structure”.

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Comparative ligand structural analytics illustrated on variably glycosylated MUC1 antigen–antibody binding

open access: yesBeilstein Journal of Organic Chemistry, 2020
When faced with the investigation of the preferential binding of a series of ligands against a known target, the solution is not always evident from single structure analysis.

The lock and key model for Molecular Recognition. Is it time for a paradigm shift? [PDF]

open access: yesarXiv, 2018
We review the standard lock and key (LK) model for binding small ligands to larger adsorbent molecule. We discuss three levels of the traditional LK model for binding. Within this model the binding constant or the Gibbs energy of the binding process is related to the total interaction energy between the ligand and the binding site of the adsorbent ...
