CARK1 phosphorylates RCAR12, RCAR13, and RCAR14. (A) Alignment of the phosphorylation sites with subfamily III receptor RCARs (R11–R14). (B–D) In vitro kinase assay. Phosphorylation of GST–RCAR12/13/14 (abbreviated as R12/13/14) by CARK1-KD (B). Phosphorylation of His-RCAR12/13/14 by CARK1-KD (C). Determination of the potential phosphorylation site of RCAR12/13/14 (D). Anti-phosphothreoinine antibody was used for the analysis of the western blot. The loading amounts of proteins were visualized on the Coomassie Brilliant Blue- (CBB) stained gel (bottom panel). Experiments were repeated at least three times.
