Ca2+ (Ca2+o ) via a dimeric extracellular Venus flytrap (VFT) unit that activates G protein-dependent signaling corresponding to heterozygous familial hypocalciuric hypercalcemia type-1 (FHH-1), supported maximal signaling In contrast, a single WT HH bundle was insufficient for maximal signaling and there was no functional Finally, we observed that the Ca2+o -stimulated CaSR operated exclusively via signaling in-trans and not via combined in-trans and in-cis signaling.

October 2022 Dimerization of β2-adrenergic receptor is responsible for the constitutive activity subjected to inverse agonism "Dimerization of beta 2-adrenergic receptor (β2-AR) has been observed across various physiologies. However, the function of dimeric β2-AR is still elusive. Here, we revealed that dimerization of β2-AR is responsible for the constitutive activity of β2-AR generating inverse agonism. Using a co-immunoimmobilization assay, we found that transient β2-AR dimers exist in a resting state, and the dimer was disrupted by the inverse agonists. A Gαs preferentially interacts with dimeric β2-AR, but not monomeric β2-AR, in a resting state, resulting in the production of a resting cAMP level. The formation of β2-AR dimers requires cholesterol on the plasma membrane. The cholesterol did not interfere with the agonist-induced activation of monomeric β2-AR, unlike the inverse agonists, implying that the cholesterol is a specific factor regulating the dimerization of β2-AR. Our model not only shows the function of dimeric β2-AR but also provides a molecular insight into the mechanism of the inverse agonism of β2-AR."

August 2022 "The calcium-permeable cation channel TRPM3 can be activated by heat and the endogenous steroid pregnenolone sulfate. TRPM3's best understood function is its role as a peripheral noxious heat sensor in mice. However, the channel is expressed in various tissues and cell types including neurons as well as glial and epithelial cells. TRPM3 expression patterns differ between species and change during development. Furthermore, a plethora of TRPM3 variants that result from alternative splicing have been identified and the majority of these isoforms are yet to be characterized. Moreover, the mechanisms underlying regulation of TRPM3 are largely unexplored. In addition, a micro-RNA gene (miR-204) is located within the TRPM3 gene. This complexity makes it difficult to obtain a clear picture of TRPM3 characteristics. However, a clear picture is needed to unravel TRPM3's full potential as experimental tool, diagnostic marker and therapeutic target. Therefore, the newest data related to TRPM3 have to be discussed and to be put in context as soon as possible to be up-to-date and to accelerate the translation from bench to bedside. The aim of this review is to highlight recent results and developments with particular focus on findings from studies involving ocular tissues and cells or peripheral neurons of rodents and humans."
