Molecular principles underlying dual RNA specificity in the Drosophila SNF protein [PDF]
, 2018 The first RNA recognition motif of the Drosophila SNF protein is an example of an RNA binding protein with multi-specificity. It binds different RNA hairpin loops in spliceosomal U1 or U2 small nuclear RNAs, and only in the latter case requires the ...

Improved Ligand-Protein Binding Affinity Predictions Using Multiple Binding Modes [PDF]
Biophysical Journal, 2010 Accurate ligand-protein binding affinity prediction, for a set of similar binders, is a major challenge in the lead optimization stage in drug development. In general, docking and scoring functions perform unsatisfactorily in this application. Docking calculations, followed by molecular dynamics simulations and free energy calculations can be applied ...

Competitive aptamer switch for modulating ligand binding affinity
Advanced Agrochem, 2023 Aptamers are short, single-stranded DNA or RNA molecules that selectively bind to a target molecule. Aptamer-complement duplex (ACD) is often used to design molecular switches capable of producing a detectable signal or triggering a structural change ...

Ca2+ binding to Chromaffin Vesicle Matrix Proteins [PDF]
, 1986 Recently we found that Ca2+ within chromaffin vesicles is largely bound [Bulenda, D., & Gratzl, M. (1985) Biochemistry 24, 7760-77651. In order to explore the nature of these bonds, we analyzed the binding of Ca2+ to the vesicle matrix proteins as well ...

3D model of amphioxus steroid receptor complexed with estradiol [PDF]
, 2009 The origins of signaling by vertebrate steroids are not fully understood. An important advance was the report that an estrogen-binding steroid receptor [SR] is present in amphioxus, a basal chordate with a similar body plan as vertebrates.

Specificity and affinity quantification of flexible recognition from underlying energy landscape topography. [PDF]
PLoS Computational Biology, 2014 Flexibility in biomolecular recognition is essential and critical for many cellular activities. Flexible recognition often leads to moderate affinity but high specificity, in contradiction with the conventional wisdom that high affinity and high ...

Dissecting the impact of target-binding kinetics of protein binders on tumor localization
iScience, 2021 Summary: Systematic control of in vivo behavior of protein-based therapeutics is considered highly desirable for improving their clinical outcomes. Modulation of biochemical properties including molecular weight, surface charge, and binding affinity has ...

Effect of thiols on beta 2-adrenoceptors in human mononuclear leucocytes [PDF]
, 1988 The effect of the disulfide reducing agent dithiothreitol (DTT) and other thiols on binding of the beta-adrenoceptor antagonist (-)-125iodocyanopindolol (125ICYP) to human mononuclear leucocytes (MNL) was investigated.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
