Activity summary

MEK1 also known as MAP2K1 is a dual-specificity kinase that plays a role in the MAPK/ERK pathway. It has a molecular weight of around 45 kDa. MEK1 phosphorylates and activates the extracellular signal-regulated kinases ERK1 and ERK2. MEK1 is expressed in various tissues but is especially abundant in brain and heart tissues. Researchers commonly measure MEK1 levels using techniques like MEK1 ELISA while phospho-MEK antibodies help analyze its activity state.

Biological function summary

MEK1 impacts cell processes such as proliferation differentiation and survival. It does not work alone but forms a complex with other proteins to exert its function. MEK1 activity is tightly controlled by upstream activators and downstream targets. One of the key phosphorylation sites on MEK1 is at serine 298 often marked as MEK1 pS298. This phosphorylation indicates MEK1's activated state which is critical for its biological function.

Pathways

MEK1 integrates signals within the MAPK/ERK pathway and interacts closely with RAF kinases upstream and ERK kinases downstream. This pathway modulates cellular responses to growth factors. MEK1 undergoes phosphorylation enhancing its activity and subsequently phosphorylates ERK proteins. Many studies isolate MEK1 activity using specific inhibitors such as the MEK1 inhibitor to dissect pathway dynamics. ERK inhibitor PD98059 also helps when studying parallel interactions with MEK1.

Associated diseases and disorders

MEK1 mutations or dysregulation have links to several types of cancer including melanoma. These often involve changes that lead to continuous MEK1 activation contributing to uncontrolled cell growth. MEK1 involvement in the RASopathies also shows its connection to disorders characterized by heart and facial abnormalities. In cancer MEK1 works closely with the BRAF protein which often harbors mutations leading to disease progression showcasing MEK1 as a target for therapeutic intervention.

    Anti-hnRNP K antibody ab18195 staining hnRNP K in HeLa cells treated with PD 98059 (ab120234), by ICC/IF. Changes in localization of hnRNP K (translocation from cytoplasm to nucleous) correlates with increased concentration of hnRNP K, as described in literature.
    The cells were incubated at 37°C for 24h in media containing different concentrations of ab120234 ( hnRNP K) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with Anti-hnRNP K antibody ab18195 (5 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
