Mitogen-activated kinase figure

Figure 11-13 (A) A simplified version of the mitogen-activated kinase (MAPK) signaling cascade. At left is shown a hormone receptor, e.g., that for the epidermal growth factor (EGF). The receptor tyrosine kinase undergoes autophosphorylation on numerous tyrosines. The resulting phosphotyrosyl (Y-P) groups bind to SH2 domains of adapters such as Grb2 and She.

Figure 11.2 Structure of the insulin receptor (a). Binding of insulin promotes autophosphorylation of the (3-subunits, where each (3-subunit phosphorylates the other (3-subunit. Phosphate groups are attached to three specific tyrosine residues (tyrosines 1158, 1162 and 1163), as indicated in (b). Activation of the (3-subunit s tyrosine kinase activity in turn results in the phosphorylation of various intracellular (protein) substrates which trigger the mitogen-activated protein kinase and/or the phosphoinositide (PI-3) kinase pathway responsible for inducing insulin s mitogenic and metabolic effects. The underlying molecular events occurring in these pathways are complex (e.g. refer to Combettes-Souverain, M. and Issad, T. 1998. Molecular basis of insulin action.

(Modified with permission from reference [11].) Note that Ras, activated via the mitogen-activated protein kinase (MAPK) pathway, may also activate PLCe. For details of the MAPK pathways and abbreviations, see Chapter 24.

Figure 21.9 The mitogen-activated protein kinase cascade (MAP kinase cascade). The active protein Ras activates Raf by promoting its recruitment to a cell membrane. Through a series of phosphorylations MAP kinase is activated as follows MAP kinase kinase kinase (Raf) phosphorylates MAP kinase kinase which, in turn, phosphorylates MAP kinase, the final target enzyme. MAP kinase phosphorylates transcription factors for genes that express proteins involved in proliferation. Another nomenclature for the enzymes is also used raf is MEKK MAPKK is MEK and finally ERK is MAP kinase (ERK is the abbreviation for extracellular-signal-related kinase) For comparison, the reader is referred to the metabolic phosphorylase cascade, which is discussed in Chapter 12 (Figure 12.12).

Figure 22.3 Signaling pathways activated by CpG DNA. CpG is thought to enter the cell via a pH-dependent step that may be receptor mediated. There is a possible role for the toll like receptor 9 (TLR-9). Once inside the cell, CpG DNA appears to act, through a number of signal transduction pathways, including the generation of reactive oxygen species (ROSs), the ubiquitination and degradation of IrcB, and activation of the mitogen-activated protein kinase (MAPK) pathways, which ultimately lead to the induction of activating protein 1 (AP-1) and nuclear factor kappa B (NF-kB).

The mitogen-activated protein kinase pathway (MAPK) on the right side of Figure 11.1 is also activated via the adaptor protein GRB-2 after insulin binds to its receptor. This activated kinase pathway eventually leads to the phosphorylation of...
