HTF-2403 Recombinant Human NKX2-3-11R Protein $300

Recombinant Human NKX2-3-11R Protein

Product Name: Recombinant Human NKX2-3-11R Protein
Catalog #:  HTF-2403
Manufacture:  LD Biopharma, Inc.

The NKX2 family of orphan homeobox proteins is composed of transcriptional factors that regulate various fundamental cellular processes, including head patterning, cardiac and lung development, and neural cell specification. Several NKX2 members including NKX2-1, NKX2-2 and NKX2- 8 function as oncogenic drivers in solid tumours, whereas NKX2-1, NKX2-2 and NKX2-5 frequently show genomic rearrangements leading to deregulated expression in T-cell acute lymphoblastic leukaemia. The homeobox NKX2-3 protein controls salivary gland, tooth and small intestine development, and has been identified as an important regulator of splenic morphology and vasculature. In fact, NKX2-3-deficient mice showed impaired distribution of B, T and follicular dendritic cells in the spleen as a consequence of abnormal homing. Recent data indicated that NKX2-3 promotes marginal-zone lymphomagenesis by activating B-cell receptor signaling and shaping lymphocyte dynamics.

Full-length human NKX2-3 cDNA (363aa) was constructed with codon optimization using gene synthesis technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal and 11 Poly-Arginine (11R) tag at its C-terminal. It was expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
