protein species itself ✅ Real-world case studies showing binding-function dissociation and residual signal It redefines how we interpret radioligand curves , shifts in signal, and the meaning of “inhibition.” Kenakin shows how even small cooperativity values (like α = 0.1) cap the shift in signal . ) β:  Dual cooperativity—how ternary complexes influence each other This framework explains partial signals irreversibility, but because there isn’t enough G protein in the system to form the species that would lower the signal

Objective: The goal of this study was to determine the glucometabolic effects of acute activation of Gs signaling We also identified two Gs-coupled GPCRs that are endogenously expressed by SKM at relatively high levels Results: Acute stimulation of GsD signaling in SKM impaired glucose tolerance in lean and obese mice The acute metabolic effects of UCN2 were not mediated by SKM Gs signaling. Conclusions: Selective activation of Gs signaling in SKM causes an acute increase in blood glucose levels

"Protecting neurons from death during oxidative and neuroexcitotoxic stress is key for preventing cognitive dysfunction. We uncovered a novel neuroprotective mechanism involving interaction between neurotrophic factor-α1 (NF-α1/carboxypeptidase E, CPE) and human 5-HTR1E, a G protein-coupled serotonin receptor with no previously known neurological function. Co-immunoprecipitation and pull-down assays confirmed interaction between NFα1/CPE and 5-HTR1E and 125I NF-α1/CPE-binding studies demonstrated saturable, high-affinity binding to 5-HTR1E in stably transfected HEK293 cells (Kd = 13.82 nM). Treatment of 5-HTR1E stable cells with NF-α1/CPE increased pERK 1/2 and pCREB levels which prevented a decrease in pro-survival protein, BCL2, during H2O2-induced oxidative stress. Cell survival assay in β-arrestin Knockout HEK293 cells showed that the NF-α1/CPE-5-HTR1E-mediated protection against oxidative stress was β-arrestin-dependent. Molecular dynamics studies revealed that NF-α1/CPE interacts with 5-HTR1E via 3 salt bridges, stabilized by several hydrogen bonds, independent of the serotonin pocket. Furthermore, after phosphorylating the C-terminal tail and intracellular loop 3 (ICL3) of NF-α1/CPE-5-HTR1E, it recruited β-arrestin1 by forming numerous salt bridges and hydrogen bonds to ICL2 and ICL3, leading to activation of β-arrestin1. Immunofluorescence studies showed 5-HTR1E and NF-α1/CPE are highly expressed and co-localized on cell surface of human hippocampal neurons. Importantly, knock-down of 5-HTR1E in human primary neurons diminished the NF-α1/CPE-mediated protection of these neurons against oxidative stress and glutamate neurotoxicity-induced cell death. Thus, NF-α1/CPE uniquely interacts with serotonin receptor 5-HTR1E to activate the β-arrestin/ERK/CREB/BCL2 pathway to mediate stress-induced neuroprotection." Read full article
