Narcissistic CLIP-170 also attracts dynactin
caffolds that hold up membrane proteins in red blood cells also support the channels needed for neuronal signaling, as shown by Lacas-Gervais et al. on page 983. Neurons fire when sodium channels clustered at the axonal initial segment (AIS) open. This depolarization is propagated by more channels clustered along axons in the Nodes of Ranvier (NR). The structure of these compartments is now sho...
متن کاملInteractions between CLIP-170, tubulin, and microtubules: implications for the mechanism of Clip-170 plus-end tracking behavior.
CLIP-170 belongs to a group of proteins (+TIPs) with the enigmatic ability to dynamically track growing microtubule plus-ends. CLIP-170 regulates microtubule dynamics in vivo and has been implicated in cargo-microtubule interactions in vivo and in vitro. Though plus-end tracking likely has intimate connections to +TIP function, little is known about the mechanism(s) by which this dynamic locali...
متن کاملGolgi/TGN cytoplasmic linker protein belonging to the CLIP-170 family
he microtubule cytoskeleton plays a fundamental role in cell organization and membrane traffic in higher eukaryotes. It is well established that molecular motors are involved in membrane–microtubule interactions, but it has also been proposed that nonmotor microtubulebinding (MTB) proteins known as CLIPs (cytoplasmic linker proteins) have basic roles in these processes. We report here the chara...

متن کاملRac1 and Cdc42 Capture Microtubules through IQGAP1 and CLIP-170
Linkage of microtubules to special cortical regions is essential for cell polarization. CLIP-170 binds to the growing ends of microtubules and plays pivotal roles in orientation. We have found that IQGAP1, an effector of Rac1 and Cdc42, interacts with CLIP-170. In Vero fibroblasts, IQGAP1 localizes at the polarized leading edge. Expression of carboxy-terminal fragment of IQGAP1, which includes ...
