Contrary to previous findings, class A GPCRs share a common activation pathway that directly links ligand binding to G-protein activation, as revealed by novel quantitative analysis.
Under normal nutritional conditions, G-protein coupled receptors can control autophagy by regulating the degradation of key autophagic regulator Atg14L through ZBTB16-mediated ubiquitination and proteasome degradation.

PTEN organizes multicellular architecture by non-catalytic scaffolding of spatially localized β-Arrestin1/ARHGAP21/Cdc42 protein complexes to control mitotic spindle orientation, multicellular configuration and lumen formation.
The cryo-EM structure of ETB-Gi complex, obtained using the Fusion-G system, provides insights into the distinct activation mechanism and G-protein promiscuity of ETB, aiding in the design of ETB agonists for therapeutic applications.
