SILu^™Prot MAPK1 Mitogen Activated Protein Kinase 1 human

SILu^™Prot MAPK1 is a recombinant, stable isotope-labeled human MAPK1 which incorporates [¹³C₆, ¹⁵N₄]-Arginine and [¹³C₆, ¹⁵N₂]-Lysine. Expressed in human 293 cells, it is designed to be used as an internal standard for bioanalysis of MAPK1 in mass-spectrometry. SILu^™Prot MAPK1 is a monomer of 380 amino acids (including polyhistidine and flag tags), with an apparent molecular weight of 44 kDa.

MAPK1 is a cytoplasmic protein that following activation is capable of translocating to the nucleus where it phosphorylates and regulates nuclear proteins (e.g., Elk-1, c-Myc, c-Jun, c-Fos, and C/EBP β). It is a protein serine/threonine kinase that is a member of the extracellular signal-regulated kinases (ERKs) which are activated in response to numerous growth factors and cytokines. Aberrations in the RAS-MAPK complex (of which MAPK1 is a downstream effector) are implicated in several human cancers, and this renders the pathway an attractive therapeutic target.
