## TL;DR

CNOT3 (CCR4-NOT transcription complex subunit 3) is a gene that drives cell growth when it is altered. The public catalogues list it as an oncogene driver, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Prostate cancer, Leukaemia, Non-Hodgkin lymphoma and 4 more.

## Summary

Component of the CCR4-NOT complex which is one of the major cellular mRNA deadenylases and is linked to various cellular processes including bulk mRNA degradation, miRNA-mediated repression, translational repression during translational initiation and general transcription regulation. Additional complex functions may be a consequence of its influence on mRNA expression. May be involved in metabolic regulation; may be involved in recruitment of the CCR4-NOT complex to deadenylation target mRNAs involved in energy metabolism.

Open Targets scores its association with cancer at 0.67 (direct and indirect evidence; datatypes affected pathway 0.33, literature 0.72, genetic association 0.00, somatic mutation 0.84, animal model 0.25). IntOGen calls it a driver in 3 cohorts (3 activating, 0 loss-of-function), covering Chronic Lymphocytic Leukaemia/Small Lymphocytic Lymphoma, Prostate Adenocarcinoma.

- Biology: Component of the CCR4-NOT complex which is one of the major cellular mRNA deadenylases and is linked to various cellular processes including bulk mRNA degradation, miRNA-mediated repression, translational repression during translational initiation and general transcription regulation. Additional complex functions may be a consequence of its influence on mRNA expression. May be involved in metabolic regulation; may be involved in recruitment of the CCR4-NOT complex to deadenylation target mRNAs involved in energy metabolism. Involved in mitotic progression and regulation of the spindle assembly checkpoint by regulating the stability of MAD1L1 mRNA. Can repress transcription and may link the CCR4-NOT complex to transcriptional regulation; the repressive function may involve histone deacetylases. Involved in the maintenance of embryonic stem (ES) cell identity. Location: Cytoplasm; Nucleus; Cytoplasm, P-body (UniProt). Locus 19q13.42 (HGNC).
- Where found: Prostate cancer: IntOGen driver in 2 cohorts (PRAD); Leukaemia: Open Targets association 0.56 with leukaemia (MONDO_0005059); Non-Hodgkin lymphoma: Open Targets association 0.55 with non-Hodgkin lymphoma (MONDO_0018908); Skin cancer: Open Targets association 0.54 with skin cancer (MONDO_0002898); Chronic lymphocytic leukaemia: IntOGen driver in 1 cohort (CLLSLL); Melanoma: Open Targets association 0.55 with melanoma (MONDO_0005105)

## 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 3 cohorts. Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
