Function

Negative regulator in the hedgehog/smoothened signaling pathway (PubMed:10559945, PubMed:10564661, PubMed:10806483, PubMed:12068298, PubMed:12975309, PubMed:15367681, PubMed:22365972, PubMed:24217340, PubMed:24311597, PubMed:27234298, PubMed:28965847). Down-regulates GLI1-mediated transactivation of target genes (PubMed:15367681, PubMed:24217340, PubMed:24311597). Down-regulates GLI2-mediated transactivation of target genes (PubMed:24217340, PubMed:24311597). Part of a corepressor complex that acts on DNA-bound GLI1. May also act by linking GLI1 to BTRC and thereby targeting GLI1 to degradation by the proteasome (PubMed:10559945, PubMed:10564661, PubMed:10806483, PubMed:24217340). Sequesters GLI1, GLI2 and GLI3 in the cytoplasm, this effect is overcome by binding of STK36 to both SUFU and a GLI protein (PubMed:10559945, PubMed:10564661, PubMed:10806483, PubMed:24217340). Negative regulator of beta-catenin signaling (By similarity). Regulates the formation of either the repressor form (GLI3R) or the activator form (GLI3A) of the full-length form of GLI3 (GLI3FL) (PubMed:24311597, PubMed:28965847). GLI3FL is complexed with SUFU in the cytoplasm and is maintained in a neutral state (PubMed:24311597, PubMed:28965847). Without the Hh signal, the SUFU-GLI3 complex is recruited to cilia, leading to the efficient processing of GLI3FL into GLI3R (PubMed:24311597, PubMed:28965847). When Hh signaling is initiated, SUFU dissociates from GLI3FL and the latter translocates to the nucleus, where it is phosphorylated, destabilized, and converted to a transcriptional activator (GLI3A) (PubMed:24311597, PubMed:28965847). Required for normal embryonic development (By similarity). Required for the proper formation of hair follicles and the control of epidermal differentiation (By similarity).

Activity summary

SUFU also known as Suppressor of Fused is a regulatory protein with a mass of approximately 54 kDa. This protein serves as a significant component within the Hedgehog signaling pathway. SUFU is widely expressed in various tissues including brain heart and skeletal muscle. It acts as a negative regulator binding to and inhibiting the activity of other key proteins in the signaling cascade.

Biological function summary

SUFU modulates the activity of the transcription factors Gli1 Gli2 and Gli3 keeping them in the cytoplasm in their inactive form. It can form part of large protein complexes playing an important role in ensuring that signal transduction is tightly regulated. SUFU's function helps control the expression of target genes that are important for development and cellular differentiation. This regulation is essential during embryonic development and tissue maintenance in adults.

Pathways

SUFU has an important role in the Hedgehog signaling pathway and interacts with components like Smoothened (SMO) and Patched (PTCH). This pathway controls processes like cell growth and differentiation. By regulating the activity of Gli proteins SUFU influences how signals are transmitted within the pathway. SUFU can also interact with other proteins such as KIF7 further defining its place within the pathway's network.

Associated diseases and disorders

SUFU can contribute to the development of basal cell carcinoma and medulloblastoma when its function is disrupted. In cases where mutations affect SUFU regulation the Hedgehog pathway becomes aberrantly activated. This can lead to uncontrolled cell proliferation. SUFU's relationship with Gli proteins is significant in these conditions because of its role in modulating their activity directly impacting the onset and progression of these cancers.

    Western blot - Anti-SUFU antibody (ab28083)

    ab28083 was shown to react with sufU in wild-type HEK293T cells in Western blot with loss of signal observed in sufU knockout cell line Human SUFU knockout HEK-293T cell line ab267282 (sufU knockout cell lysate Human SUFU knockout HEK-293T cell lysate ab257718). Wild-type HEK293T and sufU knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab28083 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with goat anti-rabbit HRP secondary antibodies at 0.2μg/mL before imaging.

    These data were provided by YCharOS Inc., an open science company with the mission of characterizing commercially available antibody reagents for all human proteins. Abcam and YCharOS are working together to help address the reproducibility crisis by enabling the life science community to better evaluate commercially available antibodies.
