General description

Mitogen activated protein kinase/ERK kinase (MEK)1 is a hydrophilic non-receptor protein and is a member of dual specificity protein kinase family. It is ubiquitously expressed. MAP2K1 is encoded by the gene mapped to human chromosome 15q22.31.

Application

MEK1, active, GST tagged human has been used to induce kinase reactions in in vitro mitogen activated protein kinase/ERK kinase (MEK)1 kinase assay. It has also been used to activate extracellular-signal-regulated kinase 2 (ERK2) by phosphorylation.

Biochem/physiol Actions

Mitogen activated protein kinase/ERK kinase (MEK)1/2 catalyzes the phosphorylation of tyrosine and then threonine in extracellular-signal-regulated kinase1/2. As an essential component of RAS−RAF−MEK−ERK signaling pathway (MAP kinase signaling cascade), it is involved in the regulation of apoptosis, cell cycle progression, cell migration, differentiation, metabolism, and proliferation. Constitutive activation of MEK1 results in cellular transformation. Thus, MEK1 represents a likely target for pharmacologic intervention in proliferative diseases such as cancer.

Physical form

Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.2 5mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol.

Hepatocellular carcinoma (HCC) is one of the most common malignancies in South East Asia. Although activation of the MEK-MAPK is often associated with cellular growth, the role of MEK-MAPK in growth and survival of hepatocarcinoma cells has not been established.

MEK1 and MEK2 are related protein kinases that participate in the RAS-RAF-MEK-ERK signal transduction cascade. This cascade participates in the regulation of a large variety of processes including apoptosis, cell cycle progression, cell migration, differentiation, metabolism, and proliferation.

Punctate palmoplantar keratoderma (PPPK) is a rare entity with an estimated prevalence rate of about 1.17 per 100,000. The exact etiology of the disorder is not known but a dual influence of genetic and environmental factors may trigger the disease.

Responses to targeted therapies frequently are brief, with patients relapsing with drug-resistant tumors. For oncogenic MEK and BRAF inhibition, drug resistance commonly occurs through activation of PI3K/AKT/mTOR signaling and immune checkpoint modulation, providing a robust molecular target for concomitant therapy.
