What is p44 p42?
The p44/42 MAPK (Erk1/2) signaling pathway can be activated in response to a diverse range of extracellular stimuli including mitogens, growth factors, and cytokines (1-3), and research investigators consider it an important target in the diagnosis and treatment of cancer (4).

What is the molecular weight of ERK2?
42 kDa
Molecular weight of MAP kinase (Erk2) protein is 42 kDa.
What do MAP kinases do?
Summary: The mitogen-activated protein kinases (MAPKs) regulate diverse cellular programs by relaying extracellular signals to intracellular responses. In mammals, there are more than a dozen MAPK enzymes that coordinately regulate cell proliferation, differentiation, motility, and survival.
Why is MAPK important?
ABSTRACT. MAPK families play an important role in complex cellular programs like proliferation, differentiation, development, transformation, and apoptosis. The above effects are fulfilled by regulation of cell cycle engine and other cell proliferation related proteins.
What is phospho Erk?
Phospho-ERK is a biomarker of response to a synthetic lethal drug combination of sorafenib and MEK inhibition in liver cancer. J Hepatol.
How do you stop MAPK pathway?
Other methods for inhibiting MAP kinase signaling pathways in treating disease include monoclonal antibodies that target extracellular domains or ligands of receptor tyrosine kinases. The use of monoclonal antibodies to block MAP kinase signaling will not be discussed and can be found in other reviews (5).
What does the MAP kinase pathway do?
MAPK pathways relay, amplify and integrate signals from a diverse range of stimuli and elicit an appropriate physiological response including cellular proliferation, differentiation, development, inflammatory responses and apoptosis in mammalian cells.
What does Ras do to Raf?
Figure 1. Ras signaling pathways. Ras forms nanoclusters and promotes Raf dimerization in the Raf/MEK/ERK (MAPK) pathway (lower left). Monomeric Raf is autoinhibited in cytosol, and the high-affinity Ras–RBD interaction releases the autoinhibition, activating Raf through side-by-side dimerization.
