HRP-3330 Recombinant YFP-Human Rab7b Protein $300

Recombinant YFP-Human Rab7b Protein

Product Name: Recombinant YFP-Human Rab7b Protein
Catalog #:  HRP-3330
Manufacture:  LD Biopharma, Inc.

Human Ras-related protein Rab-7b (Rab7b) gene encodes a protein which controls vesicular trafficking from endosomes to the trans-Golgi network (TGN). It acts as a negative regulator of TLR9 signaling and can suppress TLR9-triggered TNFA, IL6, and IFNB production in macrophages by promoting TLR9 lysosomal degradation. Rab7b also negatively regulates TLR4 signaling in macrophages by promoting lysosomal degradation of TLR4. It promotes megakaryocytic differentiation by increasing NF-kappa-B-dependent IL6 production and subsequently enhancing the association of STAT3 with GATA1. Rab7b is not involved in the regulation of the EGF- and EGFR degradation pathway. Recent data also indicated that RAb7 plays a role in controlling tumor antigen presentation process.

Full-length human Rab7b cDNA (198aa, Isoform-a) was constructed with codon optimization gene synthesis and expressed with YFP Protein as N-terminal (YFP; 256aa) fusion protein in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
