OnCo

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. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

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).
