Structural Basis of Psychedelic LSD Recognition at Dopamine D1 Receptor

Structural Basis of LSD Recognition in Dopamine D1 Receptors Research Background and Problem Statement LSD (lysergic acid diethylamide) is a well-known hallucinogen that primarily exerts profound cognitive and perceptual effects by acting on various neurotransmitter receptors, including serotonin (5-HT) receptors and dopamine receptors. The 5-HT2A ...

Conformation- and Activation-Based BRET Sensors Differentially Report on GPCR-G Protein Coupling

Differential Study of GPCR-G Protein Coupling Biosensors Background Introduction G protein-coupled receptors (GPCRs) are important molecules for transmembrane signal transduction, capable of selectively binding to heterotrimeric G proteins composed of Gα, Gβ, and Gγ subunits and regulating various intracellular signaling processes. Studying the fun...

Engineered Mini-G Proteins Block the Internalization of Cognate GPCRs and Disrupt Downstream Intracellular Signaling

Mini G Protein Inhibits Internalization of Same GPCR and Disrupts Downstream Intracellular Signaling Introduction G protein-coupled receptors (GPCRs) are the largest class of transmembrane proteins, regulating cellular responses to external stimuli such as hormones and neurotransmitters. GPCRs transmit signals by coupling with guanine nucleotide-bi...
