"Protecting neurons from death during oxidative and neuroexcitotoxic stress is key for preventing cognitive 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. cells with NF-α1/CPE increased pERK 1/2 and pCREB levels which prevented a decrease in pro-survival protein Thus, NF-α1/CPE uniquely interacts with serotonin receptor 5-HTR1E to activate the β-arrestin/ERK/CREB

While some receptors selectively activate specific G protein families, others are more versatile, yielding Apart from G proteins, GPCRs engage other effectors for signaling modulation. GPCR kinases (GRKs) and β-arrestins are activated by agonist-bound GPCRs and interact with the receptor receptor internalization. β-Arrestins facilitate this process by interacting with adapter protein 2 Nevertheless, the diverse functionalities of various GPCRs, coupled with the fluctuating expression of
