WebIn particular, investigating ciliopathies has helped us to understand the molecular mechanisms by which the cilium-associated basal body functions in early ciliogenesis, as well as how the transition zone functions in ciliary gating, and how intraflagellar transport enables cargo trafficking and signalling. WebApr 1, 2012 · As such, the inappropriate ciliary accumulation of proteins may imply an active removal pathway that is defective when the TZ is disrupted. Such a bidirectional gating is reminiscent of the nuclear pore complex, whose trafficking determinants, the Ran–Importin pathway, have been implicated in some aspects of ciliary trafficking [36].
