Short Name | SUFU-like_domain |
description | Sufu, encoding the human ortholog of Drosophila suppressor of fused, appears to have a conserved role in the repression of Hedgehog signalling []. It is a repressor of the Gli and Ci transcription factors of the Hedgehog signalling cascade [], and functions by binding these proteins and preventing their translocation to the nucleus. Sufu has been found to be a tumour-suppressor gene that predisposes individuals to medulloblastoma by modulating the SHH signalling pathway []. Homologues of Sufu have been found in bacteria, though their function is not currently known.This entry represents a domain found in Sufu and its homologues. It is also found in other proteins that are functionally uncharacterised. In eukaryotic Sufu, an additional domain () is found at the C terminus of the protein. This domain binds to the C-terminal domain of the Gli/Ci transcription factors, inhibiting their activity [].This domain is also found in Immunity protein YqcF from B. subtilis, a component of one of 6 LXG toxin-immunity modules. It neutralizes the toxic activity of cognate toxin YqcG [, ]. |
