HRP-1886 Recombinant Human Angiogenin Protein $300

Recombinant Human Angiogenin Protein

Product Name: Recombinant Human Angiogenin Protein
Catalog #:  HRP-1886
Manufacture:  LD Biopharma, Inc.

The protein encoded by human angiogenin (ANG) gene is an exceedingly potent mediator of new blood vessel formation. It hydrolyzes cellular tRNAs resulting in decreased protein synthesis and is similar to pancreatic ribonuclease. In addition, the mature peptide has antimicrobial activity against some bacteria and fungi, including S. pneumoniae and C. albicans. ANG protein binds to actin on the surface of endothelial cells; once bound, angiogenin is endocytosed and translocated to the nucleus. It stimulates ribosomal RNA synthesis including that containing the initiation site sequences of 45S rRNA. It cleaves tRNA within anti-codon loops to produce tRNA-derived stress-induced fragments (tiRNAs) which inhibit protein synthesis and triggers the assembly of stress granules (SGs). Angiogenin induces vascularization of normal and malignant tissues. Angiogenic activity is regulated by interaction with RNH1 in vivo. Recent data indicated that ANG promotes tumor cell growth and angiogenesis in solid cancers.

Full-length mature form of human angiogenin cDNA (25 – 147 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.
