In databases:

● Entrez ( 51684 or SUFU
● Ensembl ( ENSG00000107882
● UniProt ( Q9UMX1
● OMIM (  607035

● HGNC ( 16466 or SUFU

Gene locus:


Protein name:

Suppressor of fused homolog (Drosophila)

Protein Size:

484 amino acids; about 54 kDa


The Hedgehog signaling pathway plays an important role in early human development. The pathway is a signaling cascade that plays a role in pattern formation and cellular proliferation during development. The protein encoded by SUFU is a negative regulator in this Hedgehog signaling pathway.

Cancer-related alterations:

Genetic alterations in SUFU are a cause of medulloblastoma (MDB), which is a malignant, invasive embryonal tumor of the cerebellum with a preferential manifestation in children. Defects in SUFU play a role in predisposition to desmoplastic MDB. These tumors make up about 20 to 30% of medulloblastomas, have a more nodular architecture than 'classical' medulloblastoma, and may have a better prognosis.
