Activation of the p38 MAP kinase pathways is crucial for the adaptation of mammalian cells to changes in the osmolarity of the environment. Here we identify SAP97/hDlg, the mammalian homologue of the Drosophila tumour suppressor Dlg, as a physiological substrate for the p38gamma MAP kinase (SAPK3/p38gamma) isoform. SAP97/hDlg is a scaffold protein that(More)
Immediate early gene (IEG) expression is coordinated by multiple MAP kinase signaling pathways in a signal specific manner. Stress-activated p38α MAP kinase is implicated in transcriptional regulation of IEGs via MSK-mediated CREB phosphorylation. The protein kinases downstream to p38, MAPKAP kinase (MK) 2 and MK3 have been identified to regulate gene(More)
