EB1 Is Required for Primary Cilia Assembly in Fibroblasts
EB1 is a small microtubule (MT)-binding protein that associates preferentially with MT plus ends and plays a role in regulating MT dynamics. EB1 also targets other MT-associated proteins to the plus end and thereby regulates interactions of MTs with the cell cortex, mitotic kinetochores, and different cellular organelles [1, 2]. EB1 also localizes to centrosomes and is required for centrosomal ...
متن کاملCEP90 Is Required for the Assembly and Centrosomal Accumulation of Centriolar Satellites, Which Is Essential for Primary Cilia Formation
Centriolar satellites are PCM-1-positive granules surrounding centrosomes. Proposed functions of the centriolar satellites include protein targeting to the centrosome, as well as communication between the centrosome and surrounding cytoplasm. CEP90 is a centriolar satellite protein that is critical for spindle pole integrity in mitotic cells. In this study, we examined the biological functions ...
متن کاملEB1 Is Required for Spindle Symmetry in Mammalian Mitosis
Most information about the roles of the adenomatous polyposis coli protein (APC) and its binding partner EB1 in mitotic cells has come from siRNA studies. These suggest functions in chromosomal segregation and spindle positioning whose loss might contribute to tumourigenesis in cancers initiated by APC mutation. However, siRNA-based approaches have drawbacks associated with the time taken to ac...
متن کاملPericentrin forms a complex with intraflagellar transport proteins and polycystin-2 and is required for primary cilia assembly
Primary cilia are nonmotile microtubule structures that assemble from basal bodies by a process called intraflagellar transport (IFT) and are associated with several human diseases. Here, we show that the centrosome protein pericentrin (Pcnt) colocalizes with IFT proteins to the base of primary and motile cilia. Immunogold electron microscopy demonstrates that Pcnt is on or near basal bodies at...
متن کاملCPAP is required for cilia formation in neuronal cells
The primary cilium is a microtubule-based structure protruded from the basal body analogous to the centriole. CPAP (centrosomal P4.1-associated protein) has previously been reported to be a cell cycle-regulated protein that controls centriole length. Mutations in CPAP cause primary microcephaly (MCPH) in humans. Here, using a cell-based system that we established to monitor cilia formation in n...
