Protein
Tetratricopeptide repeat protein 30A
Function
Plays a role in anterograde intraflagellar transport (IFT), the process by which cilia precursors are transported from the base of the cilium to the site of their incorporation at the tip (By similarity). Required for polyglutamylation of axonemal tubulin, which is a prerequisite for correct assembly of cilia and for normal cilia beat amplitude. Does not seem to be required for neuronal microtubule polyglutamylation.
Similarity
Belongs to the TTC30/dfy-1/fleer family.
