The Ribosomal Protein S6 kinase, 90kDa, polypeptide 5 ELISA kits listed below are analytical tools for measuring concentrations of Ribosomal Protein S6 kinase, 90kDa, polypeptide 5 in various samples. Ribosomal Protein S6 kinase, 90kDa, polypeptide 5 is an alternative name for the human RPS6KA5 gene, which encodes the protein, ribosomal protein S6 kinase A5. It has been mentioned that Ribosomal Protein S6 kinase, 90kDa, polypeptide 5 plays a role in axon guidance and inflammatory response pathways, among other functions. Structurally, the RPS6KA5 protein is 802 amino acid residues in length and 89.9 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be widely expressed with high levels in heart, brain and placenta. This protein is known to be ubiquitinated and phosphorylated. Other names for this target antigen include MSK1, MSK1, and MSPK1.
