Activity summary

TRIM33 also known as TIF1γ is an E3 ubiquitin ligase involved in protein ubiquitination influencing protein stability and activity. It has a molecular mass of approximately 135 kDa. TRIM33's expression occurs widely in human tissues with higher levels found in the spleen thymus and testis. The protein contains a RING finger domain B-box type zinc fingers and coiled-coil region which are typical for the TRIM family.

Biological function summary

The ubiquitination actions of TRIM33 modulate transcriptional regulation and cell fate decisions. TRIM33 interacts with transcription factors and chromatin often forming part of the larger transcriptional regulatory complexes. Its role in repressing TGF-β signaling by ubiquitylating SMAD proteins highlights its influence on cellular growth and differentiation.

Pathways

TRIM33 has an impact on the TGF-β and BMP signaling pathways both essential for controlling cell proliferation and apoptosis. It acts in partnership with other proteins such as SMAD4 to negatively regulate TGF-β responses helping balance cellular growth. TRIM33 also interfaces with other pathway regulators like p53 influencing cell cycle and repair mechanisms.

Associated diseases and disorders

TRIM33 is linked to cancer and fibrosis. Mutations or deregulation of TRIM33 contribute to the development of leukemia where it interacts with proteins like AML1-ETO promoting leukemogenesis through altered transcriptional regulation. In pulmonary fibrosis TRIM33's interaction with SMAD3 illustrates its role in pathological signaling highlighting therapeutic potential in modulating its activity.
