The transcript encoding translationally controlled tumor protein (Tctp), a molecule associated with aggressive breast cancers, was identified among the most abundant in genome-wide screens of axons, suggesting that Tctp is important in neurons. Here, we tested the role of Tctp in retinal axon development in Xenopus laevis We report that Tctp deficiency(More)
Endocytosis and local protein synthesis (LPS) act coordinately to mediate the chemotropic responses of axons, but the link between these two processes is poorly understood. The endosomal sorting complex required for transport (ESCRT) is a key regulator of cargo sorting in the endocytic pathway, and here we have investigated the role of ESCRT-II, a critical(More)
Cyclin-dependent kinase 5 (Cdk5), a member of the cyclin-dependent kinase family, is critical for regulating neural development and neuronal survival. Dysregulation of Cdk5 is associated with abnormal expression of cell cycle-related proteins during neuronal apoptosis. We have previously found that p35, a Cdk5 activator, interacts with mSds3, an integral(More)
Local mRNA translation occurs in growing axons enabling precise control of the proteome in response to signals. To measure quantitatively the spatiotemporal dynamics of protein synthesis in growth cones, we further developed a technique for single molecule translation imaging (SMTI). We report that Netrin-1 triggers a burst of β-actin synthesis at multiple(More)
