چکیده انگلیسی
We have previously reported that the centriolar protein centlein functions as a molecular link between C-Nap1 and Cep68 to maintain centrosome cohesion [1]. In this study, we identified centlein as a novel microtubule-associated protein (MAP), directly binding to purified microtubules (MTs) via its longest coiled-coil domain. Overexpression of centlein caused profound nocodazole- and cold-resistant MT bundles, which also relied on its MT-binding domain. siRNA-mediated centlein depletion resulted in a significant reduction in tubulin acetylation level and overall fluorescence intensity of cytoplasmic MT acetylation. Centlein was further characterized in neurons. We found that centlein overexpression inhibited neurite formation in retinoic acid (RA)-induced SH-SY5Y and N2a cells. Taken together, we propose that centlein is involved in MT stability and neuritogenesis in vivo.
