Article Title: HTR6 and SSTR3 ciliary targeting relies on both IC3 loops and C-terminal tails
Journal: Life Science Alliance
doi: 10.26508/lsa.202000746

Figure Legend Snippet: Plasma membrane targeting of SSTR3 mutants. (A) The indicated SSTR3 constructs, all containing C-terminal EGFP, were expressed in IMCD3 cells and analyzed by immunofluorescence with antibodies against EGFP (green), ARL13B (red) and γ-tubulin (γTub, magenta). Cells were also stained with DAPI (DNA). All six constructs clearly reach the plasma membrane. (A, B) Indicated constructs were analyzed as in (A). IC3-mut1+CT-D335-428 mutant, lacking all but the first 10 residues in SSTR3-CT, consistently accumulates intracellularly and fails to reach plasma and ciliary membranes (left panels). In contrast, CT-mut1+IC3-D5, despite its intracellular retention frequency being much higher than normal (middle panels and Fig 7K ), can still reach ciliary and/or plasma membrane in about 60% of transfected cells (right panels). Scale bars, 5 μm.
Techniques Used: Construct, Immunofluorescence, Staining, Mutagenesis, Transfection

Figure Legend Snippet: CDK5 phosphorylation of Ser-352 in HTR6-CT does not affect HTR6 ciliary targeting. (A) IMCD3 cells expressing C-terminally EGFP-tagged Chimera J with the S352A or S352D mutations were analyzed by immunofluorescence with antibodies against EGFP (green), ARL13B (red) and γ-tubulin (γTub, magenta). DNA was stained with DAPI. Arrows indicate cilia. Scale bar, 5 μm. Serine-352 is the mouse HTR6 equivalent of human HTR6 Serine-350, shown to be a target of CDK5 phosphorylation ( 17 ). S352A and S352D are non-phosphorylatable and phosphomimetic S352 mutants, respectively. (A, B) Quantification of ciliary localization from (A). Data are mean ± SEM of n = 3 independent experiments per construct, in each of which at least 50 transfected-cell cilia were counted for each G protein-coupled receptor. No significant differences were found by one-way ANOVA.

Figure Legend Snippet: Plasma membrane targeting of HTR6 mutants. The indicated HTR6 constructs, all containing C-terminal EGFP, were expressed in IMCD3 cells, which were analyzed by immunofluorescence with antibodies against EGFP (green), acetylated tubulin (AcTub, left) or ARL13B (right) (red) and gamma-tubulin (γTub, magenta). Cells were also stained with DAPI (DNA). All HTR6 constructs clearly label the plasma membrane. Scale bar, 5 μm.
Techniques Used: Construct, Immunofluorescence, Staining

Figure Legend Snippet: HTR6 ciliary targeting requires the ciliary trafficking adapter TULP3. (A) HTR6-IMCD3 cells were transiently transfected with siRNAs targeting mouse TULP3 (siTULP3 #1 or siTULP3 #2) or firefly luciferase (siLUC) as negative control, serum-starved to promote ciliogenesis and immunostained with anti-ARL13B (green) and anti-HTR6 (red) antibodies. DNA was stained with Hoechst (blue). Scale bar, 5 μm. (A, B) HTR6 ciliary intensity was quantified from (A). Data are mean ± SEM of n = 23,32,29 cells for siLUC, siTULP3 #1, and siTULP3 #2, respectively. (C) Mouse Tulp3 mRNA levels were analyzed by qRT-PCR and expressed relative to Gapdh mRNA. Data are mean ± SEM of n = 3 independent experiments. Significance in (B, C) is shown as P
Techniques Used: Transfection, Luciferase, Negative Control, Staining, Quantitative RT-PCR

Figure Legend Snippet: HTR6 labels cilia not only more frequently but also more intensely than HTR7. (A) IMCD3 cells expressing HTR6-EGFP or HTR7-EGFP were analyzed by immunofluorescence with antibodies against EGFP (green) and ARL13B (red). DNA was stained with DAPI (blue). Scale bar, 10 μm. (A, B) Quantitation of ciliary intensity of G protein-coupled receptor-positive cilia from (A). Cilia showing no detectable G protein-coupled receptor staining were not included in the analysis (as shown in Figs 2 and 3 , HTR7 only labels about 20% of cilia, whereas HTR6 labels virtually 100%). Data are mean ± SEM of n = 42 (HTR6) and n = 31 (HTR7) cilia. Significance is shown as P
Techniques Used: Expressing, Immunofluorescence, Staining, Quantitation Assay

Figure Legend Snippet: Membrane association is needed for HTR6-CT to function as a ciliary targeting sequence. (A) IMCD3 cells expressing C-terminally EGFP-tagged HTR6-CT were analyzed by immunofluorescence with antibodies against EGFP (green), acetylated tubulin (AcTub, red) and γ-tubulin (γTub, magenta). DNA was stained with DAPI. Arrows indicate cilia. Scale bar, 5 μm. (A, B) Quantification of ciliary localization from (A). Data are mean ± SEM of n = 5 and n = 3 independent experiments for CD8α(1-206)-CT(HTR6)-EYFP and CT(HTR6)-EGFP, respectively. In each experiment, at least 50 transfected-cell cilia were counted for each construct. Significance in unpaired two-tailed t test is shown as P
Techniques Used: Sequencing, Expressing, Immunofluorescence, Staining, Transfection, Construct, Two Tailed Test
