Fluorescent Protein-Based Ca2+ Sensor Reveals Global, Divalent Cation-Dependent Conformational Changes in Cardiac Troponin C. [PDF]
PLoS ONE, 2016 Cardiac troponin C (cTnC) is a key effector in cardiac muscle excitation-contraction coupling as the Ca2+ sensing subunit responsible for controlling contraction. In this study, we generated several FRET sensors for divalent cations based on cTnC flanked

Structural Insights into Divalent Cation Modulations of ATP-Gated P2X Receptor Channels [PDF]
Cell Reports, 2016 P2X receptors are trimeric ATP-gated cation channels involved in physiological processes ranging widely from neurotransmission to pain and taste signal transduction. The modulation of the channel gating, including that by divalent cations, contributes to

Divalent Cation Modulation of Ion Permeation in TMEM16 Proteins. [PDF]
Int J Mol Sci, 2021 Intracellular divalent cations control the molecular function of transmembrane protein 16 (TMEM16) family members. Both anion channels (such as TMEM16A) and phospholipid scramblases (such as TMEM16F) in this family are activated by intracellular Ca2+ in ...

Overcoming divalent cation sensitivity is not the only challenge for functional study of ABC transporters within polymer lipid particles. [PDF]
Biosci RepProteins of the ATP-binding cassette (ABC) transporter superfamily are involved in diverse biological processes including multidrug resistance. As membrane proteins, they exist within a complex lipid environment, and often it is necessary to isolate them

Divalent Cation Removal by Donnan Dialysis for Improved Reverse Electrodialysis. [PDF]
ACS Sustain Chem Eng, 2018 Divalent cations in feedwater can cause significant decreases in efficiencies for membrane processes, such as reverse electrodialysis (RED). In RED, power is harvested from the mixing of river and seawater, and the obtainable voltage is reduced and the ...

Activation of Deoxyribonucleases by Divalent Cations [PDF]
The Journal of General Physiology, 1962 The activation of DNase I by Mg, Mn, Co, Ni, Fe, Cd, Zn, Ba, Sr, Ca, and Cu ions has been studied by several methods, at different pH and salt concentrations. Mg, Mn, and Co are the best activators for initial stages of degradation. A synergistic effect is shown only by the pair Mg-Ca. Optimal pH of action is always situated at 6.5.

Adsorption of Divalent Cations on DNA [PDF]
Biophysical Journal, 2004 The distribution of divalent ions in semidilute solutions of high-molecular-mass DNA containing both sodium chloride and strontium chloride in near-physiological conditions is studied by small-angle x-ray scattering and by small-angle neutron scattering.

Cation diffusion facilitators transport initiation and regulation is mediated by cation induced conformational changes of the cytoplasmic domain. [PDF]
PLoS ONE, 2014 Cation diffusion facilitators (CDF) are part of a highly conserved protein family that maintains cellular divalent cation homeostasis in all domains of life.

Aggregation of Nucleosomes by Divalent Cations [PDF]
Biophysical Journal, 2001 Conditions of precipitation of nucleosome core particles (NCP) by divalent cations (Ca(2+) and Mg(2+)) have been explored over a large range of nucleosome and cation concentrations. Precipitation of NCP occurs for a threshold of divalent cation concentration, and redissolution is observed for further addition of salt. The phase diagram looks similar to
