for Recombinant TRIM33 (959-1069) proteinBackground

Tripartite motif-containing 33 (TRIM33) protein, also known as TIF1γ, is a member of the transcriptional intermediary factor 1 (TIF1) family that control transcription and chromatin remodeling through their interaction with transcription factors. The family includes TRIM24 (TIF1α), TRIM28 (TIF1β) and TRIM33 (TIF1γ) that share a characteristic domain structure comprised of multiple histone-binding domains, an N-terminal TRIM region (containing a RING domain, B box type 1 and type 2 domains, and a coiled-coil region), and a C-terminal bromodomain and PHD finger. Bromodomains function as ‘readers’ of epigenetic histone marks and regulate chromatin structure and gene expression by linking associated proteins to the recognized acetylated nucleosomal targets. TRIM33 is an E3 ubiquitin protein ligase that promotes SMAD4 ubiquitination, nuclear exclusion and degradation via the ubiquitin proteasome pathway. TRIM33 does not affect SMAD4 levels but rather acts as an inhibitor of the SMAD4-dependent TGFβ/BMP signaling cascade by monoubiquitinating SMAD4 and hampering its ability to form a stable complex with activated SMAD2/3. TRIM33 may also act as a transcriptional corepressor. It has also been shown to associate with SMAD2 and SMAD3 and stimulate differentiation of hematopoietic stem cells. Additionally, TRIM33 associates with TRIM24 and plays a role in the control of cell proliferation.

TRIM33 (959-1069) protein activity assay

Recombinant TRIM33 (959-1069) protein HTRF activity assay.
1 µM H4K5/8/12/16 (ac4) peptide was incubated with different concentrations of TRIM33 (959- 1069) protein in 10 µl reaction system containing 50 mM HEPES-NaOH pH 7.5, 0.1% BSA for 1 hour, then 10 µl FLAG antibody and SA-XL665 mixture (1:100 dilution in the same buffer) was added to each reaction system and incubated for 30 min. All the operations and reactions were performed at room temperature. HTRF assay was used for detection.

for Recombinant TRIM33 (959-1069) proteinStorage

Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.
