TRIM33 is thought to be a transcriptional corepressor. However unlike the related TRIM24 and TRIM28 proteins, few transcription factors such as SMAD4 that interact with TRIM33 have been identified.[7]

Structure edit

The protein is a member of the tripartite motif family.[8] This motif includes three zinc-binding domains:

  • RING
  • B-box type 1 zinc finger
  • B-box type 2 zinc finger

and a coiled-coil region.

Three alternatively spliced transcript variants for this gene have been described, however, the full-length nature of one variant has not been determined.[7]

Interactions edit

TRIM33 has been shown to interact with TRIM24.[9]

Role in cancer edit

TRIM33 acts as a tumor suppressor gene preventing the development chronic myelomonocytic leukemia.[10] TRIM33 regulates also the TRIM28 receptor and promotes physiological aging of hematopoietic stem cells. [11] TRIM33 acts as an oncogene by preventing apoptosis in B-cell leukemias.[12]
