Configurational diversity of metabotropic glutamate receptor complexes with beta-arrestins

Beta-arrestins (β-arrs) are cytosolic proteins which mediate G protein-coupled receptor (GPCR) desensitization, endocytosis, and signaling. Despite the widespread physiological roles of β-arr coupling, the molecular basis of GPCR/β-arr interaction has been studied primarily in mo...

Nanobodies Equipped with HaloTag Enable Scalable Fluorescence-Lifetime Multiplexing

Abstract Fluorescence lifetime (FL) is a robust strategy for multiplexed imaging; however, variability in fluorophores’ local microenvironment when used on affinity probes broadens lifetime distributions, limiting its practical applicability. We create a modular platform for FL e...
