Summary: Enables RNA polymerase II-specific DNA-binding transcription factor binding activity; molecular sequestering activity; and nuclear localization sequence binding activity. Involved in cytoplasmic sequestering of protein; negative regulation of nucleocytoplasmic transport; and negative regulation of smoothened signaling pathway. Located in cytosol and nucleus. Part of protein-containing complex. Is expressed in organism. Human ortholog(s) of this gene implicated in Joubert syndrome 32; familial meningioma; medulloblastoma; and nevoid basal cell carcinoma syndrome 2. Orthologous to human SUFU (SUFU negative regulator of hedgehog signaling). [provided by Alliance of Genome Resources, Dec 2024]

A Comparison of Ci/Gli Activity as Regulated by Sufu in Drosophila and Mammalian Hedgehog Response
Title: A Comparison of Ci/Gli Activity as Regulated by Sufu in Drosophila and Mammalian Hedgehog Response.
Sufu can sequester Ci/Gli in the cytoplasm through binding to an N-terminal site while inhibiting Ci/Gli activity in the nucleus depending on a C-terminal Sufu-interacting site.
Title: Multisite interaction with Sufu regulates Ci/Gli activity through distinct mechanisms in Hh signal transduction.
Drosophila Hedgehog signaling promotes downregulation of Su(fu) through its target protein HIB (Hh-induced BTB protein).
Title: Hedgehog signaling downregulates suppressor of fused through the HIB/SPOP-Crn axis in Drosophila.
Suppressor of fused (Sufu) opposes Trn-mediated Ci nuclear import by masking its PY-nuclear localization sequence.
Title: Suppressor of fused impedes Ci/Gli nuclear import by opposing Trn/Kapβ2 in Hedgehog signaling.
The 'closed' form of Sufu is stabilized by Gli binding and inhibited by Hh treatment, whereas the 'open' state of Sufu is promoted by Gli-dissociation and Hh signaling.
Title: Structural insight into the mutual recognition and regulation between Suppressor of Fused and Gli/Ci.
Su(fu) causes the Rdx switch between two mchanisms of Cubitus interruptus regulation.
Title: Su(fu) switches Rdx functions to fine-tune hedgehog signaling in the Drosophila wing disk.
Suppressor of Fused represses Gli-mediated transcription by recruiting the SAP18-mSin3 corepressor complex.

Differential Hh target gene regulation can be accomplished by differential sensitivity of Cos2 and Su(Fu) to Hh.
