| Product Name: | Recombinant Human CD69 Protein |
| Catalog #: | HRP-1987 |
| Manufacture: | LD Biopharma, Inc. |
| Intruduction: | Human CD69 gene encodes a member of the calcium dependent lectin superfamily of type II transmembrane receptors. Expression of CD69 protein is induced upon activation of T lymphocytes, and may play a role in proliferation. Furthermore, the protein may act to transmit signals in natural killer cells and platelets. Recent data indicated that myosin light chain 9 & 12 are functional ligands for CD69 that regulate airway inflammation, blocking CD69/myosin light chain 9 & 6 interaction may provide a new strategy for the treatment of asthma. Full-length extracellular domain of human CD69 cDNA (62 – 199 aa) was constructed with codon optimization gene synthesis and expressed with a human Alpha Fetal protein N-terminal-His-TEV cleavage site Tag (217aa) fusion at FAP N-terminal. This protein 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. |
