General description
Research area: CELL SIGNALING
N-terminal GST, and C-terminal His6-tagged, recombinant full-length human MEK1
Product Source: expressed in E.coli
MEK1, also known as Mitogen-Activated Protein Kinase Kinase 1 (MAP2K1), is a protein kinase located on chromosome 15q22.1-q22.33, consisting of 12 exons and 393 amino acids. The protein is made up of two lobes containing several conserved α-helices and β-strands.

Application
Mitogen-Activated Protein Kinase Kinase 1 has been used in in vitro kinase assays:
- to elucidate the underlying mechanisms involved in the response to Rapidly Accelerated Fibrosarcoma (RAF) inhibitors and the interactions with downstream pathways.
- to investigate the role of Mitogen-Activated Protein Kinase Kinase Kinase 2 (MEKK2) as a MAP3K in the Extracellular Signal-Regulated Kinase (ERK) pathway in osteoblasts and to assess its potential as a therapeutic target for treating Neurofibromatosis Type 1 (NF1).
- to assess the effectiveness of the combined targeted therapy with Dabrafenib and Trametinib in treating non-small cell lung cancers (NSCLCs).
Biochem/physiol Actions
Protein Target: MEK1
Target Sub-Family: STE Mitogen-Activated Protein Kinase Kinase 1 (MEK1) is involved in the RAS-RAF-MEK-ERK signaling pathway. This pathway plays a crucial role in various cellular processes, including apoptosis, cell cycle progression, migration, differentiation, metabolism, and proliferation. One of its important functions is the phosphorylation of specific sites in extracellular signal-regulated kinases (ERKs) Mitogen-Activated Protein Kinase /Extracellular Signal-Regulated Kinase (MAPK3/ERK1 and MAPK1/ERK2). MEK activation is closely associated with stimulating cell growth and transformation processes.
