Descripción

Descripción general

SILu^™ Prot MAPK3 is a recombinant, stable isotope-labeled human MAPK3 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 MAPK3 in mass-spectrometry. SILu^™ Prot MAPK3 is a monomer of 399 amino acids (including N-terminal polyhistidine and flag tags), with a molecular weight of ~45.5 kDa.

Acciones bioquímicas o fisiológicas

MAPK3, the first mammalian MAPK to be characterized and cloned, is commonly expressed in most tissues and is activated through the small guanosine triphosphatase Ras and sequential activation of the protein kinases Raf and MEK upon stimulation of cells with a broad range of extracellular signals. Erk was suggested to be a good marker for estradiol and tamoxifen effects. Alzheimer′s disease′s Erk1 and Erk2 index values were inversely correlated with disease duration, suggesting maximal efficacy for early diagnosis. In addition, differential Erk1 and Erk2 phosphorylation, could have important clinical utility for providing increased certainty in the positive diagnosis of AD, particularly in the early phase of disease progression.
