Evc2 is required for the localization of Evc at the base of primary cilia. (a). RT-PCR amplification products from Evc2 null (-/-) and wild-type (+/+) MEFs. As expected, no Evc2 transcript was detected in the Evc2 null MEFs. A significant amount of Evc transcript was amplified in the Evc2 null MEF sample. Hprt transcript was amplified as a control. (b). Western blot analysis of Evc protein in Evc2 null MEFs. The amount of β-actin detected on the same blot was used as a loading control. Evc (approximately 130 kDa) is present in Evc2 null (-/-) MEFs despite having reduced levels (approximately 50%) (c). Representative immunofluorescent staining of Evc in MEF cells. Despite the presence of protein, Evc (red) was not detected at the base of primary cilia in Evc2 null MEFs (-/-). Primary cilia were identified by the presence of acetylated tubulin (green) and nuclei stained with DAPI (blue). Scale bar 10 μm.
