Anti-MAPKAPK1B antibodies enable researchers to detect and measure the MAPKAPK1B antigen in biological samples. This target is a reported synonym of the RPS6KA3 gene, which encodes ribosomal protein S6 kinase A3. This protein is known to function in the cell cycle and nervous system development, among other biological roles. The human version of MAPKAPK1B has a canonical amino acid length of 740 residues and a protein mass of 83.7 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include CLS, CLS, and HU-3. Western Blot is the most common application for the MAPKAPK1B antibodies listed below. ELISA and Immunohistochemistry are also common applications.
