Functionally distinct and selectively phosphorylated GPCR subpopulations co-exist in a single cell. [PDF]
, 2018 G protein-coupled receptors (GPCRs) transduce pleiotropic intracellular signals in a broad range of physiological responses and disease states. Activated GPCRs can undergo agonist-induced phosphorylation by G protein receptor kinases (GRKs) and second ...

Signaling diversity of PKA achieved via a Ca2+-cAMP-PKA oscillatory circuit [PDF]
Nature Chemical Biology, 2010 Many protein kinases are key nodal signaling molecules that regulate a wide range of cellular functions. These functions may require complex spatiotemporal regulation of kinase activities. Here, we show that protein kinase A (PKA), Ca(2+) and cyclic AMP (cAMP) oscillate in sync in insulin-secreting MIN6 beta cells, forming a highly integrated ...

Tailoring the Properties of Functional Materials With N‐Oxides
Advanced Functional Materials, EarlyView.The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Theoretical study on the protonation of AZA-aromatics [PDF]
, 1975 The protonation of azanaphthalenes and azabenzenes has been studied theoretically using CNDO/2 wavefunctions and perturbation theory in order to examine the correlation between pKa values and quantum-mechanical ...

Croatica Chemica Acta, 2018 A novel approach – termed here as biphasic pKa values – is presented for quantifying the acidity/basicity of lipophilic compounds embedded in water-immiscible media (membranes or solutions) at equilibrium with aqueous solution. In this approach the hydrogen ion activity is determined in the aqueous phase, while the concentration ratio of protonated and
