Cell proliferation is regulated in several contexts, for example during development, tissue differentiation, wound healing and immune responses. In mammalian cells, proliferative signals lead to the activation of a protein kinase cascade, resulting in the phosphorylation of two closely related Mitogen-Activated Protein Kinases (MAPK’s) ERK1 and ERK2 of 44 kDa and 42 kDa, respectively.  When activated, ERK’s form dimers that translocate to the nucleus where they phosphorylate several classes of transcription factors which are involved in the up-regulation of immediate early genes.  As such, ERK1 and ERK2 represent a paradigm for a growing family of proline-directed protein kinases that mediate entry, progression and exit from the cell cycle in diverse eukaryotic cells. These enzymes function within highly conserved cascade of sequentially activating protein kinases that transduce signals from diverse extracellular stimuli.  Alternative splice transcript variants encoding different protein isoforms have been described. ERK1 and ERK2 are phosphorylated within the activation loop on both a Threonine and a Tyrosine residue (within a Thr-Glu-Tyr motif) by MEKs (MAPK/ERK kinases), thereby greatly elevating the activity of ERK1&2.

Conjugated Peptide
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to the carboxy terminal end of human p44 MAP Kinase (ERK1) protein.
This affinity-purified antibody is directed against the human p44 MAP Kinase (ERK1) protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification.  A BLAST analysis was used to suggest cross reactivity with p44 MAP Kinase (ERK1) proteins from human, bovine, rabbit, rat and mouse. No reactivity is observed against p42 MAP Kinase (ERK2). Reactivity against homologues from other sources is not known.

Application Details

This affinity purified antibody has been tested for use in ELISA, immunoprecipitation and by western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a predominant band approximately 44 kDa in size corresponding to p44 MAP Kinase (ERK1) by western blotting in the appropriate cell lysate or extract.
