Past studies had indicated that targeting MK2 to block its downstream events could be equivalent to direct inhibition of upstream p38α (responsible for MK2 activation) of the p38MAPK pathway, with the additional advantage of lacking any p38-dependent side effects [138,139]. This is the reason ...
RAS/RAF/MAPK can be activate via two pathways: (1) a ligand-dependent pathway, in which ligands, such as growth factors, hormones, or cytokines, physically engage with receptors; and (2) a ligand-independent pathway, in which signaling is induced by a physical stressor, such as radiation, ...
Scaffold proteins of the mitogen-activated protein kinase (MAPK) pathway have been proposed to form an active signaling module and enhance the specificity of the transduced signal. Here, we report a 2-Å resolution structure of the MAPK scaffold protein MP1 in a complex with its partner ...

【4】However, in contrast to the activation mechanisms described above, a MAP3K is sometimes phosphorylated by a MAP4K (Dan et al., 2001;Champion et al., 2004) (Figure 1A). For example, yeast Ste20 acts as...
MAPK7(ERK5). Originally called BigMAP kinaseor BMK1 because of its C-terminal domain that gives rise to a protein twice the size of ERK1/2.It is activated in a complex composed ofMAP2K2and MAP3K2, kinases that normally operate in the “p38 pathway.” It is essential for growth factor...
Full size image RMZL inhibited the activation of the MAPK/ERK pathway in H/R treated hepatocyte Given that MAPK/ERK signaling has been associated with the regulation of I/R damage [17], we examined whether RMZL affects the MAPK/ERK signaling status in hepatocytes. Compared to the control gr...
Full size image Results Inactivation of the CIP MAPK pathway causes hypersensitivity to MT damage Carbendazim (MBC) is commonly used in yeasts to induce depolymerization of MTs, thus compromising the formation of the mitotic spindle and the ensuing process of chromosome capture [51]. This engages ...
Tumorigenesis requires that cells hijack regulatory networks to obtain their full oncogenic potential. The MAPK (mitogen-activated protein kinase) pathway is a tightly regulated signaling cascade frequently mutated or deregulated in cancer. Extra- and intracellular stimuli activate the MAPK cascade that reg...
The ERK1/2 cascade was the first MAPK pathway elucidated [11], and is considered as a prototype of these kinase cascades. This cascade plays a central role in the signaling of a wide variety of extracellular agents that operate via various receptors. In most cases, the activation of such ...
