General description

A cell-permeable benzoyl dihydroquinazolinone derivative that acts as a reversible and specific blocker of AAA+ ATPase motor cytoplasmic dynein and disrupts spindle pole focusing, cold-stable microtubule formation, kinetochore-microtubule attachment, and melanosome aggregation in a dose-dependent manner (~10 to 40 µM). Shown to perturb protein trafficking within the primary cilia and cause a significant increase in intraflagellar transport protein 88 (IFT88) levels at the distal tip of primary cilia. Reported to disrupt primary cilium-dependent Gli regulation and block Hedgehog signaling.

Components of the intraflagellar transport (IFT) system that regulates the assembly of the primary cilium are co-opted by the non-ciliated T cell to orchestrate polarized endosome recycling and to sustain signaling during immune synapse formation. Here, we investigated the potential

ARL13B is a regulatory GTPase highly enriched in cilia. Complete loss of Arl13b disrupts cilia architecture, protein trafficking and Sonic hedgehog signaling. To determine whether ARL13B is required within cilia, we knocked in a cilia-excluded variant of ARL13B (V358A) and
