Adaptive evolution of transcription factor binding sites [PDF]

open access: yesBMC Evolutionary Biology, 2004
Background The regulation of a gene depends on the binding of transcription factors to specific sites located in the regulatory region of the gene. The generation of these binding sites and of cooperativity between them are essential building blocks in ...

Locating ligand binding sites in G-protein coupled receptors using combined information from docking and sequence conservation [PDF]

open access: yesPeerJ, 2021
GPCRs (G-protein coupled receptors) are the largest family of drug targets and share a conserved structure. Binding sites are unknown for many important GPCR ligands due to the difficulties of GPCR recombinant expression, biochemistry, and ...

Inferring binding energies from selected binding sites. [PDF]

open access: yesPLoS Computational Biology, 2009
We employ a biophysical model that accounts for the non-linear relationship between binding energy and the statistics of selected binding sites. The model includes the chemical potential of the transcription factor, non-specific binding affinity of the ...

Interaction of haemin with albumin-based macroporous cryogel: Adsorption isotherm and fluorescence quenching studies

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Albumin-based cryogels for capturing haemin were synthesised by crosslinking different biomolecules, bovine serum albumin (BSA) and ovalbumin (OVA). The impact of the protein and coupling agent concentrations on cryogel’s mechanical properties, swelling ...

Binding sites analyser (BiSA): software for genomic binding sites archiving and overlap analysis. [PDF]

open access: yesPLoS ONE, 2014
Genome-wide mapping of transcription factor binding and histone modification reveals complex patterns of interactions. Identifying overlaps in binding patterns by different factors is a major objective of genomic studies, but existing methods to archive ...

Monolayer Gas Adsorption on Graphene-Based Materials: Surface Density of Adsorption Sites and Adsorption Capacity

open access: yesSurfaces, 2020
Surface density of adsorption sites on an adsorbent (including affinity-based sensors) is one of the basic input parameters in modeling of process kinetics in adsorption based devices.

Novel Three-Finger Neurotoxins from Naja melanoleuca Cobra Venom Interact with GABAA and Nicotinic Acetylcholine Receptors

open access: yesToxins, 2021
Cobra venoms contain three-finger toxins (TFT) including α-neurotoxins efficiently binding nicotinic acetylcholine receptors (nAChRs). As shown recently, several TFTs block GABAA receptors (GABAARs) with different efficacy, an important role of the TFTs ...

Interplay Between Lipid Modulators of Kir2 Channels: Cholesterol and PIP2

open access: yesComputational and Structural Biotechnology Journal, 2014
We have shown earlier that Kir2 channels are suppressed by the elevation of membrane cholesterol. Moreover, it is also well known that activation of Kir channels is critically dependent on a regulatory phospholipid, phosphatidylinositol-4,5-bisphosphate (
