Protein Kinases as Substrates for SAPKs,nases – MNKs, and as MAPK-activated protein kinases – MAPKAPKsor MKs. Although their kinase domains are phylogenetically related and show some similarities in regulation,the downstream kinases regulate gene expression at different levels, which contribute to orchestration ofthe stress response.

Control of mRNA Stability by SAPKs,onmentand changes in the half-lives of mRNAs is regulated by the activity of stress activated MAP kinases (SAPKs)and their substrates. Here, we will describe some of those mechanisms, and how SAPKs regulate mRNA stabilityin eukaryotic cells.

Modeling the Dynamics of Stress Activated Protein Kinases (SAPK) in Cellular Stress Response,he modelingprocess and introduce basic concepts for dynamic model analysis. We briefly review basic dynamic propertiesof stress activated protein (SAP) or mitogen activated protein (MAP) kinase (K) cascades that demonstratewhy this type of signaling pathways is so abundantly used in cellular information processing and response.
