Target Details

Target Function	Implicated in nucleolar organization, ribosome biogenesis, protein synthesis and cytoplasmic dsRNA sensing. Stimulates RNA polymerase I transcription of the 47S precursor rRNA. Associates with ribosomal DNA (rDNA) loci where it is involved in POLR1A recruitment. In the cytoplasm, promotes elongation-competent 80S ribosome assembly at the late stage of mRNA translation initiation. Senses cytosolic dsRNA mediating NLRP3 inflammasome formation in macrophages and type I interferon production in myeloid dendritic cells. Required for NLRP3 activation induced by viral dsRNA and bacterial RNA. In dendritic cells, required for induction of type I interferon production induced by cytoplasmic dsRNA via the activation of MAPK and NF-kappa-B signaling pathways.
Subcellular Location	Nucleus, nucleolus. Nucleus, nucleoplasm. Cytoplasm. Nucleus. Inflammasome.
Protein Families	DEAD box helicase family, DEAH subfamily
Database References	HGNC: 16718 OMIM: 614405 KEGG: hsa:56919 STRING: 9606.ENSP00000225296 UniGene: Hs.250456

Gene Functions References

DHX33 doublet is due to alternative translation initiation by two in-frame initiation codons. DHX33 translation initiation from either AUG codon happens at equal efficiency. Short DHX33 protein has similar cellular location and functions with full-length DHX33. Leaky scanning normally occurs in DHX33 mRNA translation, which may serve as a safeguard mechanism to ensure optimal DHX33 translation efficiency. PMID: 29864424
In clinical samples, the expression of Rab1A or DHX33 was reversely correlated with miR-634. Re-expression of Rab1A or DHX33 abrogated the miR-634-mediated inhibition of cell proliferation and migration. Collectively, our data suggest a tumor suppressor role of miR-634 in hepatocellular carcinoma. PMID: 27693040
High expression of DHX33 is associated with non-Hodgkin's lymphoma and acute myeloid leukemia. PMID: 28498893
Study demonstrates that DHX33 acts as a direct transcriptional regulator to promote cell cycle progression and plays an important role in driving cell proliferation during both embryo development and tumorigenesis. PMID: 27601587
Our data therefore suggest DHX33 is overexpressed in HCC and serves as a promising prognostic biomarker for this deadly disease. PMID: 27073163
The results reveal a newly recognized function of DHX33 in mRNA translation initiation, further solidifying its central role in promoting cell growth and proliferation. PMID: 26100019
Data indicate that DHX33 forms the inflammasome complex with NLRP3 following stimulation with cytosolic RNA. PMID: 23871209
results directly implicate DHX33 as a crucial player in establishing rRNA synthesis rates in the face of Ras(V12) or ARF signals, adjusting ribosome biogenesis to match the appropriate growth or antigrowth signals. PMID: 23401854
we show the mechanistic importance of DHX33 in rRNA transcription and proliferation PMID: 21930779

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
