MAPK Signaling Scientific Review
MAP kinase signaling is integral to the regulation of numerous cellular processes such as proliferation and differentiation, and as a result is an important focus of cancer and immunology research. Updated for 2016, this review discusses the regulation of the MAPK pathway and properties of MAPK cascades. Compounds available from Tocris are listed.
