Phosphorylation of GLI3 by PKA on up to six sites in the C-terminal region primes the protein for subsequent phosphorylation by CK1 and GSK3 and is required for the ubiquitin-mediated processing by the proteasome to yield the truncated repressor form (Tempe et al, 2006; Pan et al, 2006; Pan and Wang, 2007; Wang and Li, 2006). Processing of GLI3 is regulated in part by movement through the primary cilia, and disruption of intraflagellar transport abrogates processing (Wen et al, 2010)
