Summary: Predicted to enable ubiquitin protein ligase activity. Predicted to contribute to ubiquitin-protein transferase activity. Involved in positive regulation of proteasomal ubiquitin-dependent protein catabolic process and protein ubiquitination. Acts upstream of or within labyrinthine layer blood vessel development and spongiotrophoblast layer development. Part of Cul7-RING ubiquitin ligase complex and SCF ubiquitin ligase complex. Is expressed in several structures, including heart; liver; lung; placenta; and spleen. Orthologous to human FBXW8 (F-box and WD repeat domain containing 8).

FBXW8 and PARK2 are sequestrated into insolubility by ATXN2 PolyQ expansions, but only FBXW8 expression is dysregulated
Title: Both ubiquitin ligases FBXW8 and PARK2 are sequestrated into insolubility by ATXN2 PolyQ expansions, but only FBXW8 expression is dysregulated.
mTORC2 negatively feeds back to IRS-1 via control of Fbw8 stability and localization.
Title: mTOR complex 2 regulates proper turnover of insulin receptor substrate-1 via the ubiquitin ligase subunit Fbw8.
our data support the concept that expanded ATXN2 undergoes progressive insolubility and affects PABPC1 by a toxic gain-of-function mechanism with tissue-specific effects, which may be partially alleviated by the induction of FBXW8.
Title: ATXN2-CAG42 sequesters PABPC1 into insolubility and induces FBXW8 in cerebellum of old ataxic knock-in mice.
Depletion of FBXW8 caused a significant accumulation of cyclin D1, as well as sequestration of CDK1 in the cytoplasm. This resulted in a severe reduction of cell proliferation.
Title: A critical role for FBXW8 and MAPK in cyclin D1 degradation and cancer cell proliferation.
FBXW8-CUL7 complex plays a significant role in growth control
Title: Disruption of the Fbxw8 gene results in pre- and postnatal growth retardation in mice.
Cul7 forms a heterodimeric complex with Cul1 in a manner dependent on Fbxw8.
Title: Fbxw8 is essential for Cul1-Cul7 complex formation and for placental development.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
