In this complex, Ci becomes phosphorylated in a series of steps catalyzed by PKA, GSK3β, and CK1.

The phosphorylated Ci is proteolytically cleaved by the ubiquitin-proteasome pathway, generating an N-terminal fragment Ci75, which functions as a transcriptional repressor of Hh target genes.

Hh binds to Ptc, causing Ptc to be endocytosed from the cell surface and degraded, relieving the inhibition of Smo.
