ARMC9 is localised to the basal body of a cilium and is upregulated during ciliogenesis [1,2]. It is required for appropriate acetylation and polyglutamylation of ciliary microtubules, and regulation of cilium length [1]. This entry represents the armadillo repeats found towards the C-terminal ARMC9 [1].
