MIB2
MIB2 (E3 ubiquitin-protein ligase MIB2) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Head and neck squamous cell carcinoma.
Overview
E3 ubiquitin-protein ligase that mediates ubiquitination of Delta receptors, which act as ligands of Notch proteins. Positively regulates the Delta-mediated Notch signalling by ubiquitinating the intracellular domain of Delta, leading to endocytosis of Delta receptors.
IntOGen calls it a driver in 1 cohort (0 activating, 1 loss-of-function), covering Head and Neck Squamous Cell Carcinoma.

MIB2 (E3 ubiquitin-protein ligase MIB2) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Head and neck squamous cell carcinoma.
- 2 · What goes wrong in cancer
E3 ubiquitin-protein ligase that mediates ubiquitination of Delta receptors, which act as ligands of Notch proteins.
- 3 · How drugs use it
No product in this corpus aims at MIB2 yet. Because the protein is lost rather than overactive, drugs either restore its function or exploit the weakness its loss leaves (synthetic lethality).

Notes
top- 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 a loss-of-function (LoF) driver in 1 cohort. Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
