FUBP1

Chr 1

far upstream element binding protein 1

Also known as: FBP, FUBP, hDH V

NCBI Gene: 8880 ENSG00000162613 UniProt: Q96AE4

The protein regulates MYC expression by binding to a far-upstream DNA element and can both activate and repress transcription. Mutations cause intellectual disability and seizures with autosomal dominant inheritance. The gene is highly constrained against loss-of-function variants (pLI 1.0, LOEUF 0.115), indicating that complete loss of function is likely incompatible with normal development.

ResearchSummary from UniProt

The protein encoded by this gene is a single stranded DNA-binding protein that binds to multiple DNA elements, including the far upstream element (FUSE) located upstream of c-myc. Binding to FUSE occurs on the non-coding strand, and is important to the regulation of c-myc in undifferentiated cells. This protein contains three domains, an amphipathic helix N-terminal domain, a DNA-binding central domain, and a C-terminal transactivation domain that contains three tyrosine-rich motifs. The N-terminal domain is thought to repress the activity of the C-terminal domain. This protein is also thought to bind RNA, and contains 3'-5' helicase activity with in vitro activity on both DNA-DNA and RNA-RNA duplexes. Aberrant expression of this gene has been found in malignant tissues, and this gene is important to neural system and lung development. Binding of this protein to viral RNA is thought to play a role in several viral diseases, including hepatitis C and hand, foot and mouth disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

Interpreting a novel variant

This gene is strongly intolerant of loss-of-function variation in the population, so LoF variants warrant close attention. No curated mechanism annotation is available — see the mechanism card for the computational prediction and its caveats.Based on population constraint only.
