The full-length Phh-grd variants and Phh-lcch3 were amplified using GoTaq polymerase (Promega) and cloned in the pTB207 expression vector using the In-Fusion HD Cloning Kit (Takara Bio Europe SAS, Saint-Germain-en-Laye, France) as described (Lamassiaude et al., 2021 (link)). Recombinant plasmids were purified using E.Z.N.A. Plasmid DNA Mini Kit (Omega Bio-Tek, Inc., Norcross, GA), and correct cloning was confirmed by sequencing (Eurofins Genomics). cRNAs were obtained from plasmids linearized by Msc1 (Thermo Fisher Scientific) using mMessage mMachine T7 transcription kit (Thermo Fisher Scientific) following the manufacturer's instructions. cRNA concentrations were measured by spectrophotometry (NanoDrop; Thermo Fisher Scientific), and integrity of cRNAs was confirmed by running 500 ng in 1% agarose gel in TAE buffer (40 mM Tris-acetate–1 mM EDTA).
