Studies in the Chlamydomonas model system has shown that the ciliary protein CEP290 is a critical component of these Y-link junctions. Additionally, numerous studies have demonstrated that CEP290’s function is critical for IFT—in CEP290 knockdown experiments, many proteins that would normally localize to the cilium fail to do so, and cilium formation is disrupted or absent. Mutations in CEP290 are accountable for cases of nephronophthisis, Leber congenital amaurosis and Joubert syndrome. In IF analtsis of HeLa cells, the white arrows show centrosome and cilium staining. Two isoforms were produced by alternative splicing with predicted MW of 290 and 180 kDa according to UniProt. Catalog#22490-1-AP can recognise both.

Human RPE1 cell line with Methanol fixation.Immunostaining result shows that CEP290 localizes to centrosome (Red; CEP290, Green; CEP164 for Centrosome marker, Blue;DAPI for Nucleus).The antibody seems to detect additional nucleoli signals.
