MAPK1(ERK2) shares high homology with MAPK3(ERK1). MAP kinase phosphatase as a locus of flexibility in a mitogen-activated protein kinase signaling network. Mitogen-activated protein(MAP) kinases [also known as Erks] have been established to function as important mediators of signal transduction by growth factor receptors. ERK1/ERK2-dependent activation of endogenous ribosomal transcription, while inactivation of ERK1/ERK2 causes an equally immediate reversion to the basal transcription level. ERK1/ERK2 was found to phosphorylate the architectural transcription factor UBF at amino acids 117 and 201 within HMG boxes 1 and 2, preventing their interaction with DNA. Mutation of these sites inhibited transcription activation and abrogated the transcriptional response to ERK1/ERK2.
The stated application concentrations are suggested starting amounts. Titration of the MAPK1/3 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
An amino acid sequence from the N-terminus of human MAPK1/3 (ARVADPDHDHTGFL) was used as the immunogen for this MAPK1/3 antibody (100% homologous in human, mouse and rat).
After reconstitution, the MAPK1/3 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
