| Product Name | MSK1 (phospho Ser360) Rabbit mAb |
| Background | Catalytic activity: ATP + a protein = ADP + a phosphoprotein. Cofactor: Magnesium. Enzyme regulation: Appears to be activated by multiple phosphorylations on threonine and serine residues. ERK1/2 and MAPK14/p38-alpha may play a role in this process.,function:Serine/threonine kinase required for the mitogen or stress-induced phosphorylation of the transcription factors CREB (cAMP response element-binding protein) and ATF1 (activating transcription factor-1). Essential role in the control of RELA transcriptional activity in response to TNF. Directly represses transcription via phosphorylation of 'Ser-1' of histone H2A. Phosphorylates 'Ser-10' of histone H3 in response to mitogenics, stress stimuli and epidemal growth-factor (EGF), which results in the transcriptional activation of several immediate early genes, including proto-oncogenes c-fos/FOS and c-jun/JUN. May also phosphorylate 'Ser-28' of histone H3. Mediates the mitogen- and stress-induced phosphorylation of high mobility group protein 14 (HMG-14). Miscellaneous:Enzyme activity requires the presence of both kinase domains. PTM: Ser-376 and Thr-581. Phosphorylation is required for kinase activity. Ser-376 and Ser-212 are autophosphorylated by the C-terminal kinase domain, and their phosphorylation is essential for the catalytic activity of the N-terminal kinase domain. Similarity: Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily. Similarity:Contains 1 AGC-kinase C-terminal domain.,similarity:Contains 2 protein kinase domains. Subcellular location: Predominantly nuclear. Partially cytoplasmic. Subunit: Forms a complex with either ERK1 or ERK2 in quiescent cells which transiently dissociates following mitogenic stimulation. Also associates with MAPK14/p38-alpha. Activated RPS6KA5 associates with and phosphorylates the NF-kappa-B p65 subunit RELA. Ttissue specificity: Widely expressed with high levels in heart, brain and placenta. Less abundant in lung, kidney and liver. |
