Structure of Recombinant Human RAB27B Protein

The recombinant form of RAB27B protein is produced through genetic engineering techniques using a host organism, such as bacteria or yeast. The resulting protein is identical to the natural form of RAB27B and has a similar structure. It consists of 207 amino acids and has a molecular weight of approximately 23 kDa. The protein contains a conserved GTP-binding domain and a C-terminal geranylgeranylation motif, which are essential for its function.

Activity of Recombinant Human RAB27B Protein

RAB27B protein is primarily involved in regulating vesicle trafficking and exocytosis. It functions as a molecular switch, cycling between an active GTP-bound form and an inactive GDP-bound form. In its active form, RAB27B interacts with various effector proteins, which mediate its downstream effects. These include the regulation of vesicle transport, docking, and fusion with the target membrane. RAB27B also plays a crucial role in controlling the secretion of hormones, enzymes, and other signaling molecules from cells.

The activity of recombinant RAB27B protein has been extensively studied in various cell types, including immune cells, pancreatic cells, and neuronal cells. In immune cells, RAB27B is involved in the secretion of cytokines and chemokines, which are essential for the immune response. In pancreatic cells, RAB27B regulates the release of insulin, a hormone that controls blood sugar levels. In neuronal cells, RAB27B plays a role in neurotransmitter release, which is vital for proper brain function.

Applications of Recombinant Human RAB27B Protein

The unique properties and functions of recombinant RAB27B protein make it a valuable tool in various applications. One of the primary uses of this protein is in the study of vesicle trafficking and exocytosis.
