Trafficking to the primary cilium membrane
The primary cilium has been found to be associated with a number of cellular signaling pathways, such as vertebrate hedgehog signaling, and implicated in the pathogenesis of diseases affecting multiple organs, including the neural tube, kidney, and brain. The primary cilium is the site where a subset of the cell's membrane proteins is enriched. However, pathways that target and concentrate memb...
متن کاملA role for Rab23 in the trafficking of Kif17 to the primary cilium.
The small GTPase Rab23 is an antagonist of sonic hedgehog (Shh) signaling during mouse development. Given that modulation of Shh signaling depends on the normal functioning of the primary cilium, and overexpression of Evi5L, a putative Rab23 GTPase-activating protein (GAP), leads to reduced ciliogenesis, Rab23 could have a role at the primary cilium. Here, we found that wild-type Rab23 and the ...
متن کاملSmoothened Adopts Multiple Active and Inactive Conformations Capable of Trafficking to the Primary Cilium
Activation of Hedgehog (Hh) signaling requires the transmembrane protein Smoothened (Smo), a member of the G-protein coupled receptor superfamily. In mammals, Smo translocates to the primary cilium upon binding of Hh ligands to their receptor, Patched (Ptch1), but it is unclear if ciliary trafficking of Smo is sufficient for pathway activation. Here, we demonstrate that cyclopamine and jervine,...
متن کاملSignaling through the Primary Cilium
The presence of single, non-motile "primary" cilia on the surface of epithelial cells has been well described since the 1960s. However, for decades these organelles were believed to be vestigial, with no remaining function, having lost their motility. It wasn't until 2003, with the discovery that proteins responsible for transport along the primary cilium are essential for hedgehog signaling in...
متن کاملHedgehog signaling from the primary cilium to the nucleus: an emerging picture of ciliary localization, trafficking and transduction.
The unexpected connection between cilia and signaling is one of the most exciting developments in cell biology in the past decade. In particular, the Hedgehog (Hh) signaling pathway relies on the primary cilium to regulate tissue patterning and homeostasis in vertebrates. A central question is how ciliary localization and trafficking of Hh pathway components lead to pathway activation and regul...
