## TL;DR

FBXO11 (F-box only protein 11) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Colorectal cancer, Endometrial cancer, Ovarian cancer and 5 more.

## Summary

Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins, such as DTL/CDT2, BCL6, SNAI1 and PRDM1/BLIMP1. The SCF(FBXO11) complex mediates ubiquitination and degradation of BCL6, thereby playing a role in the germinal centre B-cells terminal differentiation toward memory B-cells and plasma cells. The SCF(FBXO11) complex also mediates ubiquitination and degradation of DTL, an important step for the regulation of TGF-beta signalling, cell migration and the timing of the cell-cycle progression and exit.

CIViC holds 1 clinical evidence item and 0 assertions across 1 variant. Open Targets scores its association with cancer at 0.83 (direct and indirect evidence; datatypes literature 0.96, animal model 0.49, genetic association 0.87, somatic mutation 0.97). IntOGen calls it a driver in 5 cohorts (1 activating, 4 loss-of-function), covering Burkitt Lymphoma, Malignant Lymphoma, Non-Hodgkin Lymphoma.

- Biology: Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins, such as DTL/CDT2, BCL6, SNAI1 and PRDM1/BLIMP1.

The SCF(FBXO11) complex also mediates ubiquitination and degradation of DTL, an important step for the regulation of TGF-beta signalling, cell migration and the timing of the cell-cycle progression and exit. The SCF(FBXO11) complex also catalyses ubiquitination and degradation of GSK3B-phosphorylated SNAI1. Binds to and neddylates phosphorylated p53/TP53, inhibiting its transcriptional activity. Plays a role in the regulatiom of erythropoiesis but not myelopoiesis or megakaryopoiesis. Location: Nucleus; Chromosome (UniProt). Locus 2p16.3 (HGNC).

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: IntOGen calls it an activating (Act) driver in 1 cohort; IntOGen calls it a loss-of-function (LoF) driver in 4 cohorts; CIViC holds 1 clinical evidence items on its variants. Evidence tier "clinical-evidence" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
