[https://www.uniprot.org/uniprot/TRI33_HUMAN TRI33_HUMAN] Papillary or follicular thyroid carcinoma. The disease is caused by mutations affecting the gene represented in this entry. A chromosomal aberration involving TRIM33 is found in thyroid papillary carcinomas. Translocation t(1;10)(p13;q11) with RET. The translocation generates the TRIM33/RET (PTC7) oncogene. | |||

[https://www.uniprot.org/uniprot/TRI33_HUMAN TRI33_HUMAN] 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 signaling cascade. Plays a role in the control of cell proliferation. Its association with SMAD2 and SMAD3 stimulates erythroid differentiation of hematopoietic stem/progenitor (By similarity). Monoubiquitinates SMAD4 and acts as an inhibitor of SMAD4-dependent TGF-beta/BMP signaling cascade (Monoubiquitination of SMAD4 hampers its ability to form a stable complex with activated SMAD2/3 resulting in inhibition of TGF-beta/BMP signaling cascade).<ref>PMID:10022127</ref> <ref>PMID:15820681</ref> <ref>PMID:16751102</ref> <ref>PMID:19135894</ref> | |||
