TRIM33 (E3 ubiquitin-protein ligase TRIM33) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor and a fusion partner, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Lung cancer, Breast cancer, Colorectal cancer and 1 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

Acts as an E3 ubiquitin-protein ligase. Promotes SMAD4 ubiquitination, nuclear exclusion and degradation via the ubiquitin proteasome pathway. According to PubMed:16751102, does not promote a decrease in the level of endogenous SMAD4. May act as a transcriptional repressor. Inhibits the transcriptional response to TGF-beta/BMP signalling cascade. Plays a role in the control of cell proliferation. Location: Nucleus (UniProt). Locus 1p13.2 (HGNC).
