Once activated, Ras can do a variety of things. In this example, it activates an enzymatic cascade of MAP kinases ... activates an enzyme called a kinase. Learn how kinases initiate a signaling ...

MAP2K1 mutations have been functionally classified into three groups according to their dependency on upstream RAS/RAF signaling. However, the clinical efficacy of mitogen-activated protein kinase ...

Panel A summarizes the conventional model of how oncogenic RAS ... kinase (ERK). AF6 denotes afadin, GAP GTPase-activating protein, GEF guanine exchange factor, MEK mitogen-activated protein ...

Spatiotemporal network dynamics govern cell fate decisions. We use the extracellular signal-regulated kinase (ERK) pathway as a paradigm to describe how temporal activation kinetics and spatial ...

In contrast, the signal proceeds normally or with greater strength (because of compensatory hyperinsulinemia of various degrees) along the Shc-Ras-MAP kinase pathway, eliciting greater responses ...

"Rasopathies are a group of rare genetic disorders that are caused by mutations in genes that regulate the Ras/mitogen-activated protein kinase (MAPK) signaling pathway." "Given the rarity of this ...
