Figure Lengend Snippet: (A) Relative Git1 intensity in the Smo-TurboID proteomic results. (B) Git1 is biotinylated by Smo-TurboID independent of Shh treatment. Smo-V5-TurboID stable cells were infected with lentiviruses expressing YFP-Git1. Cells were treated with Shh for 1h, and cell lysates were used for purification with Streptavidin beads. a-Tubulin is used as loading control. (C) Git1 localizes to the basal body. NIH3T3 cells were transfected with YFP-Git1, and stained for primary cilium (Arl13b, red), basal body (Pericentrin, magenta), and nucleus (DAPI, blue). In addition to its putative distribution in the cytosol, Git1 also localizes to the basal body. Scale bar, 5 μm, 2 μm (inset). (D, F) Immunofluorescence imaging of Smo and phosphorylated Smo (pSmo) in WT and Git1-null cells. The cells are treated with 1 μg/ml recombinant Shh or vehicle.

(E, G) Quantification of ciliary Smo and pSmo immunofluorescence intensity (AU). n = 100-150 cells/condition from three biological replicates. (H) Representative images of immunofluorescence staining in Smo-TurboID cells transfected with control shRNA or shRNA against Git1.

Figure Lengend Snippet: (A) guide RNA was designed to target exon 2 of mouse Git1 . (B) The gRNA targeting region in mouse genomic was amplified by genomic PCR, ligated into TOPO vector, and transfected into chemically competent cells. 20 bacterial colonies of each cell clones were randomly picked and sequenced. The Sanger sequencing results were aligned with the genome sequence of the M. musculus. Single base pair deletion and insertion are identified, resulting in biallelic frameshift or early termination. (C) Immunoblot of Git1-null cell lines showing that Git1 protein is not detected in knockout cells. GAPDH is used as the loading control. (D) Cilium staining in WT and Git1-null cell colonies. Primary cilium is marked with Arl13b (red). Scale bar, 10 μm. (E) Quantification of cilium length, n = 60 cells/condition from 3 biological replicates. (F) Git1 transcript levels in cells transfected with shRNA against Git1. Statistics in (E-F): one-way ANOVA followed by Sidak’s multiple comparisons test. *p < 0.01, ***p < 0.001, ****p < 0.0001, ns, not significant.

Figure Lengend Snippet: (A) Experimental workflow of GNP primary culture and treatment. (B) qPCR measurement of Git1 transcript levels in GNPs at the end of the experiment. (C) Hh signaling intensity is assessed by Gli1 transcript levels in GNPs at the end of the experiment. (D) Immunostaining of Edu (magenta) incorporation in primary cultured GNPs. Cells are infected with lentivirus expressing control or Git1 shRNA. (E) quantification of Edu incorporation into the GNP nucleus. n = 10 fields for each condition. (F) Schematic view of Git1’s function in Hh signaling. Git1 at the ciliary base facilitates Grk2’s interaction with Smo; it also promotes Grk2 translocation into the cilium to effectively phosphorylate Smo. Without Git1, Grk2 fails to phosphorylate Smo, leading to reduced Hh signaling. Data in B, C, E are shown as Mean ± SD. Statistics: two-way ANOVA followed by Tukey’s multiple comparison test. *p < 0.01, ***p < 0.001, ****p < 0.0001, ns, not significant.
