HRP-1665 Recombinant Human RAB33b Protein $300

Recombinant Human RAB33b Protein

Product Name: Recombinant Human RAB33b Protein
Catalog #:  HRP-1665
Manufacture:  LD Biopharma, Inc.

Endocytosis is involved in a wide variety of cellular processes, including uptake and internalization of solutes and components of the extracellular matrix (ECM), regulation of signaling induced by extracellular ligands, trafficking of cell surface receptors, such as integrins, and rearrangement of the actin cytoskeleton. Endocytosis and intracellular trafficking are coordinated by a family of small GTPases termed the Rabs. Rab proteins are classified according to their function and localization in different intracellular compartments and membrane domains. Rab33b, a member of the Rab small GTPase family that was originally described as a Golgi-resident protein involved in Golgi-to-endoplasmic reticulum (ER) transport, directly interacts with Atg16L in a guanosine triphosphate (GTP)-dependent manner and that activation and inactivation of RAb33b modulate autophagy pathway.

Full-length human Rab33b cDNA (227 aa, Isoform-I, derived from BC036064) 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.
