Anti-MSK2 antibodies enable researchers to detect and measure the MSK2 antigen in biological samples. This target is a reported synonym of the RPS6KA4 gene, which encodes ribosomal protein S6 kinase A4. This protein is known to function in inflammatory response pathways and intracellular signal transduction, among other biological roles. The human version of MSK2 has a canonical amino acid length of 772 residues and a protein mass of 85.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include RSK-B and S6K-alpha-4. Western Blot is a widely used application for the MSK2 antibodies listed below. In addition, ELISA is also a common application.
