HTF-1631 Recombinant Human IRF4 Protein $200

Recombinant Human IRF4 Protein

Product Name: Recombinant Human IRF4 Protein
Catalog #:  HTF-1631
Manufacture:  LD Biopharma, Inc.

The protein encoded by human interferon regulatory factor 4 (IRF4) gene belongs to the IRF (interferon regulatory factor) family of transcription factors, characterized by an unique tryptophan pentad repeat DNA-binding domain. The IRFs are important in the regulation of interferons in response to infection by virus, and in the regulation of interferon-inducible genes. This family member is lymphocyte specific and negatively regulates Toll-like-receptor (TLR) signaling that is central to the activation of innate and adaptive immune systems. A chromosomal translocation involving this gene and the IgH locus, t(6;14)(p25;q32), may be a cause of multiple myeloma. Alternatively spliced transcript variants have been found for this gene.

Full-length human IRF4 (450 aa, derived from BC015752) gene was constructed with 29 aa N-terminal T7 / His / TEV cleavage site Tag and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
