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.

Ligand-gated ion channels (LGICs) are natural biosensors generating electrical signals in response to the binding of specific ligands. Creating de novo LGICs for biosensing applications is technically challenging. We have previously designed modified LGICs by linking G protein-coupled receptors (GPCRs)
