Anti-RALB antibodies are used in the immunodetection of the protein RAS like proto-oncogene B. In humans, the canonical protein has a reported length of 206 amino acid residues and a mass of 23.4 kDa. Its subcellular localization is in the cell membrane. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the testis, placenta, parathyroid gland, ovary, and bone marrow. A member of the Ras protein family, RALB is known to be a Multifunctional GTPase involved in a variety of cellular processes including gene expression, cell migration, cell proliferation, oncogenic transformation and membrane trafficking. Synonyms for this target antigen include RALB Ras like proto-oncogene B, RAS-like protein B, ras related GTP binding protein B, v-ral simian leukemia viral oncogene homolog B (ras related; GTP binding protein), and ras-related protein Ral-B. A number of RALB antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
