Phosphorylation of BOK at Ser-8 Blocks Its Ability to Suppress IP3R-Mediated Calcium Mobilization

The New Role of BOK Protein in Calcium Signaling Regulation Background Introduction BOK (Bcl-2-related ovarian killer) is a member of the Bcl-2 protein family and has long been thought to play a role in cell apoptosis. However, recent studies suggest that BOK may also have non-apoptotic functions, particularly in the regulation of calcium ion (Ca²⁺...

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...
