Function

Dual specificity protein kinase which acts as an essential component of the MAP kinase signal transduction pathway. Binding of extracellular ligands such as growth factors, cytokines and hormones to their cell-surface receptors activates RAS and this initiates RAF1 activation. RAF1 then further activates the dual-specificity protein kinases MAP2K1/MEK1 and MAP2K2/MEK2. Both MAP2K1/MEK1 and MAP2K2/MEK2 function specifically in the MAPK/ERK cascade, and catalyze the concomitant phosphorylation of a threonine and a tyrosine residue in a Thr-Glu-Tyr sequence located in the extracellular signal-regulated kinases MAPK3/ERK1 and MAPK1/ERK2, leading to their activation and further transduction of the signal within the MAPK/ERK cascade. Activates BRAF in a KSR1 or KSR2-dependent manner; by binding to KSR1 or KSR2 releases the inhibitory intramolecular interaction between KSR1 or KSR2 protein kinase and N-terminal domains which promotes KSR1 or KSR2-BRAF dimerization and BRAF activation (PubMed:29433126). Depending on the cellular context, this pathway mediates diverse biological functions such as cell growth, adhesion, survival and differentiation, predominantly through the regulation of transcription, metabolism and cytoskeletal rearrangements. One target of the MAPK/ERK cascade is peroxisome proliferator-activated receptor gamma (PPARG), a nuclear receptor that promotes differentiation and apoptosis. MAP2K1/MEK1 has been shown to export PPARG from the nucleus. The MAPK/ERK cascade is also involved in the regulation of endosomal dynamics, including lysosome processing and endosome cycling through the perinuclear recycling compartment (PNRC), as well as in the fragmentation of the Golgi apparatus during mitosis.

Activity summary

MEK1 and MEK2 also known as MAP2K1 and MAP2K2 respectively are dual-specificity kinases that play roles in signaling pathways mediating cellular responses. MEK1 and MEK2 have molecular weights of approximately 45kDa. They are expressed in various tissues including the heart brain and skeletal muscles reflecting their widespread function within the organism. These proteins are often referred collectively as the MEK1/2 complex due to their shared and overlapping roles in cell signaling.

Biological function summary

MEK1 and MEK2 are integral parts of the mitogen-activated protein kinase (MAPK) signaling cascade. MEK1/2 phosphorylate and activate the ERK1/2 kinases which transmit signals from the cell surface to the nucleus regulating gene expression and cell fate decisions. The MEK1/2 proteins also act in concert with other kinases and substrates forming signaling complexes that ensure specific and regulated cellular outcomes.

Pathways

MEK1 and MEK2 play key roles within the MAPK/ERK pathway a critical signaling mechanism for cell division and survival. They also link to the RAS/MAPK pathway involved in transmitting signals from membrane receptors to the nucleus. In these pathways MEK1/2 interact with proteins like RAF kinases and ERK1/2 propagating signals that influence cellular growth and differentiation.

Associated diseases and disorders

MEK1 and MEK2 are implicated in cancer and neurological disorders. Abnormal activity of the MEK1/2 proteins often due to mutations can lead to uncontrolled cell proliferation contributing to the development of cancers such as melanoma. In neurological disorders dysregulation of MEK1/2 signaling relates to conditions like neuro-cardio-facial-cutaneous syndromes. These proteins interact with other key players in these diseases such as mutant RAF proteins in melanoma highlighting their critical roles in disease mechanisms.
