PRKMK1

Uses

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.

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.

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.
