WebJul 13, 2015 · Meckelin (MKS3) functions in ciliogenesis and ciliary gating. MKS3 appears to have similar functions in Paramecium tetraurelia, i.e. FLAG-MKS3 is found associated slightly above each basal body and RNAi for MKS3 leads to loss of cilia. RNAi for MKS3 also leads to the disorganization of rows of basal bodies that run from anterior to … 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. dicks north little rock ar
