Summary: Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; cAMP response element binding protein binding activity; and protein homodimerization activity. Involved in several processes, including animal organ development; regionalization; and regulation of transcription by RNA polymerase II. Located in cytosol; membrane; and nucleus. Part of Hedgehog signaling complex. Is expressed in several structures, including ectoderm; ectoderm anlage; embryonic epidermis; extended germ band embryo; and imaginal disc. Used to study primary bacterial infectious disease. Human ortholog(s) of this gene implicated in several diseases, including Culler-Jones syndrome; Pallister-Hall syndrome; anodontia; holoprosencephaly 9; and synostosis (multiple). Orthologous to several human genes including GLI2 (GLI family zinc finger 2) and GLI3 (GLI family zinc finger 3). [provided by Alliance of Genome Resources, Apr 2022]

Multisite interaction with Sufu regulates Ci/Gli activity through distinct mechanisms in Hh signal transduction.
Title: Multisite interaction with Sufu regulates Ci/Gli activity through distinct mechanisms in Hh signal transduction.
Ci responds to and relays Hh signals in a precise manner to control target genes expressions and ensures proper Hh signal transduction.
Title: Decoding Ci: from partial degradation to inhibition.
findings reveal a conserved mechanism by which Ci/Gli is stabilized by a deubiquitination enzyme and identify Usp7/HUASP as a critical regulator of Hh signaling
Title: Deubiquitination of Ci/Gli by Usp7/HAUSP Regulates Hedgehog Signaling.
Data show that normal Ci-155 activation by Hh requires Cos2 binding to Fu, supporting the hypothesis that Cos2 mediates the apposition of Fu molecules suitable for cross-phosphorylation and consequent full activation of Fu kinase.
