The Disordered Region of ASXL1 Acts as an Auto‐Regulator Through Condensation
Advanced Science, EarlyView.ASXL1's long IDR encodes an electrostatic “basic platform + acidic brake” that autoregulates condensation. Truncation at a clinical hotspot lifts this brake, forming condensates that retarget BRD2, remodel local chromatin accessibility, and impair neutrophil maturation.

Three classes of ligands each bind to distinct sites on the orphan G protein-coupled receptor GPR84 [PDF]
, 2017 Medium chain fatty acids can activate the pro-inflammatory receptor GPR84 but so also can molecules related to 3,3′-diindolylmethane. 3,3′-Diindolylmethane and decanoic acid acted as strong positive allosteric modulators of the function of each other and

Quantifying Correlations Between Allosteric Sites in Thermodynamic Ensembles [PDF]
Journal of Chemical Theory and Computation, 2009 Allostery describes altered protein function at one site due to a perturbation at another site. One mechanism of allostery involves correlated motions, which can occur even in the absence of substantial conformational change. We present a novel method, "MutInf", to identify statistically significant correlated motions from equilibrium molecular ...

Precision Editing of NLRS Improves Effector Recognition for Enhanced Disease Resistance
Advanced Science, EarlyView.Precision engineering of plant NLR immune receptors enables rational design of enhanced pathogen resistance through mismatched pairing, domain swapping, and targeted mutagenesis. These approaches achieve multi‐fold expansion in recognition breadth while minimizing autoimmunity risks and fitness penalties.

Studying early structural changes in SOS1 mediated KRAS activation mechanism
Current Research in Structural BiologyKRAS activation is known to be modulated by a guanine nucleotide exchange factor (GEF), namely, Son of Sevenless1 (SOS1). SOS1 facilitates the exchange of GDP to GTP thereby leading to activation of KRAS.

The calcium-sensing receptor as a regulator of cellular fate in normal and pathological conditions [PDF]
, 2013 The calcium-sensing receptor (CaSR) belongs to the evolutionarily conserved family of plasma membrane G protein-coupled receptors (GPCRs). Early studies identified an essential role for the CaSR in systemic calcium homeostasis through its ability to ...

Machine learning approaches in predicting allosteric sites
Current Opinion in Structural BiologyAllosteric regulation is a fundamental biological mechanism that can control critical cellular processes via allosteric modulator binding to protein distal functional sites. The advantages of allosteric modulators over orthosteric ones have sparked the development of numerous computational approaches, such as the identification of allosteric binding ...
