Anti-Rab22B antibodies enable researchers to detect and measure the Rab22B antigen in biological samples. This target is a reported synonym of the RAB31 gene, which encodes RAB31, member RAS oncogene family. This protein is known to function in insulin signaling pathways and intracellular protein transport, among other biological roles. The human version of Rab22B has a canonical amino acid length of 194 residues and a protein mass of 21.6 kilodaltons. It is reported to be localized in the cytoplasmic vesicles and Golgi of cells and widely expressed in many tissue types. Rab22B is a member of the Rab protein family.
