Author response image 1. ARL13B-RAB23S23N fusion protein is present in the cilia of Arl13bhnn MEFs.
Arl13bhnn MEFs transfected with ARL13B-RAB23S23N, ARL13B-GFP, or control plasmid. (A) The ARL13BRAB23 S23N fusion protein is detectable in the cilium (acetylated a-tubulin, magenta) by ARL13B antibody (cyan, NeuroMab). (B) Wildtype ARL13B-GFP is present in the cilium in high- (left column) and low- (right column) expressing cells. (C) No ARL13B positive cilia were detected in control plasmid transfected cells. (D) Secondary only controls.
