Homeostatic Noise Buffering in Biomolecular Condensates Hinges on Phase Multiplicity Modulated by Interfacial and Droplet Size Effects
Jonas Wessén, Tanmoy Pal, Suman Das +1
Specific mixing or demixing of molecular species is a characteristic feature of condensed intracellular membraneless compartments. How sequence patterns of intrinsically disordered…
Differential Effects of Sequence-Local versus Nonlocal Charge Patterns on Phase Separation and Conformational Dimensions of Polyampholytes as Model Intrinsically Disordered Proteins
Tanmoy Pal, Jonas Wessén, Suman Das +1
Conformational properties of intrinsically disordered proteins (IDPs) are governed by a sequence-ensemble relationship. To differentiate the impact of sequence-local versus sequenc…
Electrostatics of Salt-Dependent Reentrant Phase Behaviors Highlights Diverse Roles of ATP in Biomolecular Condensates
Yi-Hsuan Lin, Tae Hun Kim, Suman Das +6
Liquid-liquid phase separation (LLPS) involving intrinsically disordered protein regions (IDRs) is a major physical mechanism for biological membraneless compartmentalization. The…
PT-Symmetry Breaking Transitions in Polymeric Systems
Tanmoy Pal, Ranjan Modak, Bhabani Prasad Mandal
We show that classical DNA unzipping transition which is equivalently described by quantum mechanical localization-delocalization transition in the ground state of non-Hermitian si…
Analytical Formulation and Field-Theoretic Simulation of Sequence-Specific Phase Separation of Proteinlike Heteropolymers with Short- and Long-Spatial-Range Interactions
Jonas Wessén, Suman Das, Tanmoy Pal +1
A theory for sequence dependent liquid-liquid phase separation (LLPS) of intrinsically disordered proteins (IDPs) in the study of biomolecular condensates is formulated by extendin…
Field theory description of ion association in re-entrant phase separation of polyampholytes
Jonas Wessén, Tanmoy Pal, Hue Sun Chan
Phase separation of several different overall neutral polyampholyte species (with zero net charge) is studied in solution with two oppositely charged ion species that can form ion-…
Numerical Techniques for Applications of Analytical Theories to Sequence-Dependent Phase Separations of Intrinsically Disordered Proteins
Yi-Hsuan Lin, Jonas Wessén, Tanmoy Pal +2
Biomolecular condensates, physically underpinned to a significant extent by liquid-liquid phase separation (LLPS), are now widely recognized by numerous experimental studies to be…
A Simple Explicit-Solvent Model of Polyampholyte Phase Behaviors and its Ramifications for Dielectric Effects in Biomolecular Condensates
Jonas Wessén, Tanmoy Pal, Suman Das +2
Biomolecular condensates such as membraneless organelles, underpinned by liquid-liquid phase separation (LLPS), are important for physiological function, with electrostatics -- amo…
Subcompartmentalization of polyampholyte species in organelle-like condensates is promoted by charge pattern mismatch and strong excluded-volume interaction
Tanmoy Pal, Jonas Wessén, Suman Das +1
Polyampholyte field theory and explicit-chain molecular dynamics models of sequence-specific phase separation of a system with two intrinsically disordered protein (IDP) species in…
Rigidity of Melting DNA
Tanmoy Pal, Somendra M. Bhattacharjee
The temperature dependence of DNA flexibility is studied in the presence of stretching and unzipping forces. Two classes of models are considered. In one case the origin of elastic…
Efimov like phase of a three stranded DNA (Efimov-DNA) and the renormalization group limit cycle
Tanmoy Pal, Poulomi Sadhukhan, Somendra M. Bhattacharjee
A three-stranded DNA with short range base pairings only is known to exhibit a classical analog of the quantum Efimov effect, viz., a three chain bound state at the two chain melti…
Renormalization Group Limit Cycle for Three-Stranded DNA
Tanmoy Pal, Poulomi Sadhukhan, Somendra M. Bhattacharjee
We show that there exists an Efimov-like three strand DNA bound state at the duplex melting point and it is described by a renormalization group limit cycle. A nonperturbative RG i…
