Figure 4.

Tmem231, B9d1, and Tctn1 are required for TZ MKS complex formation. Ciliary TZ of Tmem231 (A), B9d1 (B), and Tctn1 (C) wild-type and mutant MEFs, stained for γ-tubulin (red), TubAc (blue), and either Tmem231, B9d1, Mks1, Tmem67, Rpgrip1l, or Nphp1 (green). Tmem231 and B9d1 are necessary for Mks1 and Tmem67 but not Rpgrip1L or Nphp1 localization. Tctn1 is required for both Tmem231 and B9d1 localization. TZs are denoted by white arrowheads. Bars, 2.5 µm. Quantitation of TZ fluorescence intensity from at least 10 cilia are shown next to each set of images. Error bars represent the 95% confidence interval. *, P < 0.05, as measured by Student’s t test with Welch’s correction. (D) Tmem231 wild-type and mutant bile duct, kidney, pancreas, retina, and trachea stained for B9d1 (green), TubAc (red), and DAPI (blue). (E) B9d1 wild-type and mutant bile duct, kidney, pancreas, retina, and trachea stained for Tmem231 (green), TubAc (red), and DAPI (blue). Bars: (full field) 10 µm; (inset) 2.5 µm.
