β-Arrestin droplets control the function of G-protein-coupled receptors
Generation of Constructs Constructs were created using a modified technique for overlap cloning. Flexible linkers made of glycine-serine repeats (GGGGS), varying in length from 18 to 33 amino acids, were added between coding sequences for fluorescent proteins or luciferases and the receptors, transducers, biosensors, or adaptor proteins. The mutants of SmBiT-β-arrestin IP6, AP2, and clathrin […]
Carnitine production driven by αKG supports DNA repair through histone acetylation
Cells and culture conditions The Ovcar8, JHOS4, Uwb1.289, and PEO1 cell lines were provided by Benjamin Bitler at the University of Colorado. Ovcar8 cells were grown in RPMI 1640 medium (Gibco, 11875119) with 5% fetal bovine serum (FBS; BioWest, S1620) and 1% penicillin-streptomycin (Fischer Scientific, 15-140-122). JHOS4 cells were maintained in a 1:1 mix of […]
