The protein encoded by this gene is thought to be a transcriptional corepressor. However unlike the related TIF1-α and TIF1-β proteins, few transcription factors such as Smad4 that interact with TIF1-γ have been identified.[5]

Structure

The protein is a member of the tripartite motif family.[7] 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.[5]

Interactions

TRIM33 has been shown to interact with TRIM24.[8]

Role in cancer

TRIM33 acts as a tumor suppressor gene preventing the development chronic myelomonocytic leukemia.[9] TRIM33 regulates also the TGF-β1 receptor and promotes physiological aging of hematopoietic stem cells. [10] TRIM33 acts as an oncogene by preventing apoptosis in B-cell leukemias.[11]
