Subcellular Localization of CEP164 and SDCCAG8 by Immunofluorescence (A) CEP164 colocalizes with the mother centriole (labeled with γ-tubulin), the mitotic spindle poles (actetylated tubulin), and the midbody throughout the cell cycle in hTERT-RPE cells. Whereas in the centriole-engaged state (upper panel) γ-tubulin antibody labels both centrioles, the α-CEP164 antibody only labels one centriole (the mother centriole) in hTERT cells. Immunofluorescence of endogenous CEP164 was performed in hTERT cells. Cells were fixed (4% PFA), permeabilized (0.1% SDS) and immuno-stained with antibody anti-CEP164-NR (red) and costained with anti-γ-tubulin or anti-acetylated tubulin antibodies (green). DAPI was used to label DNA (Blue). Scale bars, 2.5 μm. (B)–(D) Upon immunofluorescence (IF) in hTERT-RPE cells antibody α-SDCCAG8-CG recognizes nuclear foci that are absent upon transient SDCCAG8/NPHP10 knockdown. Left panels show transfected hTERT-RPE cells, middle panels show IF with α-SDCCAG8-CG, right panels show merge of left and middle panels. Antibody α-SDCCAG8-CG recognizes nuclear foci in hTERT-RPE cells (middle and right panels). (B) hTERT cells transiently transfected with GFP-labeled negative control shRNA construct exhibit nuclear foci upon IF with α-SDCCAG8-CG (arrow heads in right panel), whereas in cells transfected with GFP-labeled SDCCAG8 shRNA knockdown constructs pGIPZ-259547 (C) or pGIPZ-90858 (D) nuclear foci are absent (asterisks in right panels of (C) and (D), demonstrating specificity of the nuclear foci signal detected by α-SDCCAG8-CG. Scale bars, 5 μm. See also Figure 4.
