Recombinant Human ATIA Protein

Product Name: Recombinant Human ATIA Protein
Catalog #:  hRP-1787
Manufacture:  LD Biopharma, Inc.

The regulation of apoptosis is critical for controlling tissue homeostasis and preventing tumor formation and growth. Reactive Oxygen Species (ROS) generation plays a key role in such regulation. Human ATIA (anti-TNFa-induced apoptosis) protects cells again TNFa and Hypoxia-induced apoptosis. ATIA gene is highly expressed in some tissues including liver, lung, heart, and testis. The human ortholog of ATIA, vasorin, was reported to be a potential inhibitor of TGFβ signaling with a possible role in angiogenesis. Recent data indicated that ATIA is highly expressed in human glioblastoma, and ATIA knockdown in glioblastoma cells renders them sensitive to hypoxia-induced apoptosis.

Full-length extracellular domain of human ATIA cDNA (24 – 575aa, derived from BC068575) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its 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.
