MAPK8 - mitogen-activated protein kinase 8 Gene
Also Known as JNK; JNK1; PRKM8; SAPK1; JNK-46; JNK1A2; SAPK1c; JNK21B1/2
Species: Homo sapiens
About MAPK8
This gene has 16 transcripts (splice variants), 291 orthologues and 19 paralogues. Ubiquitous expression in brain (RPKM 9.4), thyroid (RPKM 7.2) and 25 other tissues.
Summary
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. Several alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Apr 2016]
