Western blot analysis of MAPK8 over-expressed 293 cell line, cotransfected with MAPK8 Validated Chimera RNAi ( Cat # H00005599-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with MAPK8 monoclonal antibody (M11) clone 2F11 (Cat # H00005599-M11 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
The protein encoded by this gene is a member of the MAP kinase family. MAP kinases act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase is activated by various cell stimuli, and targets specific transcription factors, and thus mediates immediate-early gene expression in response to cell stimuli. The activation of this kinase by tumor-necrosis factor alpha (TNF-alpha) is found to be required for TNF-alpha induced apoptosis. This kinase is also involved in UV radiation induced apoptosis, which is thought to be related to cytochrom c-mediated cell death pathway. Studies of the mouse counterpart of this gene suggested that this kinase play a key role in T cell proliferation, apoptosis and differentiation. Four alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq
