    Rsk-1 Antibody (T12A6) is a mouse monoclonal IgG2a antibody that detects Rsk-1 in human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and immunohistochemistry. Rsk-1, also known as MAPKAP kinase-1, is a crucial serine/threonine kinase that serves as a key signaling intermediate in various cellular responses to ligand-activated receptor tyrosine kinases. Rsk-1 features two non-identical complete kinase catalytic domains, allowing Rsk-1 to integrate multiple signaling pathways effectively. This structural complexity is essential for mediating cellular processes such as growth, differentiation, and survival, particularly in response to stress signals. Rsk-1 is predominantly expressed in tissues such as the brain and kidney, where Rsk-1 contributes to normal neuronal development and function. The ability of Rsk-1 to interact with other signaling proteins further underscores Rsk-1′s importance in cellular signaling networks, making anti-Rsk-1 antibody (T12A6) an invaluable tool for researchers studying the intricate mechanisms of cell signaling and its implications in various diseases.
