Krs-2 Antibody (RJ-5) is a mouse monoclonal IgG1 antibody that detects Krs-2 in mouse, rat, and human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Krs-2, also known as MST-2, is a member of the mammalian Ste20-like kinase family, which plays a crucial role in cellular signaling pathways that regulate cell growth, survival, and apoptosis. Krs-2 is primarily located in the cytoplasm and can translocate to the nucleus under certain conditions, which is significant for its function in mediating stress responses and promoting cell survival. Krs-2 is known to interact with various signaling molecules, including caspase-3, which Krs-2 activates, thereby influencing apoptotic pathways. Krs-2′s ability to phosphorylate substrates and itself is essential for regulatory functions in the MAPK signaling cascade, making Krs-2 a vital component in the cellular response to external stimuli. With broad species reactivity and versatility in multiple applications, anti-Krs-2 antibody (RJ-5) is an invaluable tool for researchers studying the intricate roles of this kinase in health and disease.
