Fig. 7. FAP133 Requires DHC1b and D1bLIC for localization to the peri-basal body region. (A) Whole-cell extracts from wild-type (CC124), dhc1b, d1blic and fla14 cells, were either stained with Coomassie Blue (upper panel) or analyzed by immunoblotting, using antibodies against FAP133, DHC1b, D1bLIC and LC8 (lower panels). (B) Indirect immunofluorescence microscopy of wild-type (CC124), dhc1b, d1blic and fla14 cells using the antibody against FAP133. FAP133 is located primarily at the peri-basal body region in wild-type and fla14 cells but not in the dhc1b or d1blic mutants where it is found in the cytoplasm, concentrated near the middle of the cell.
