HRP-1669 Recombinant Human RAB39 Protein $300

Recombinant Human RAB39 Protein

Product Name: Recombinant Human RAB39 Protein
Catalog #:  HRP-1669
Manufacture:  LD Biopharma, Inc.

Phagocytosis of pathogens by macrophages is an important process of the innate immune response. Pathogens are enveloped by phagocytic membranes to form phagosomes immediately following internalization. The phagosomes are then processed by a series of interactions with endosomes, resulting in phagosome maturation. During phagosome maturation, phagosomes fuse with lysosomes, in a process known as phagolysosome biogenesis, and acquire degradative and microbicidal properties. At least 22 Rab GTPases localize on the phagosome transiently or consecutively during progression of phagosome maturation, with Rab7, Rab20 and Rab39 regulating acidification of the phagosome.

Full-length human Rab39 cDNA (216 aa, Isoform-II, derived from BC028064) 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.
