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.  In vertebrates the mitogen-induced sequential activation of the kinases Raf1->Mek1->Erk2->Rsk occurs via the G-protein Ras.

Human, Mouse
Recombinant Protein
Anti-Erk2 antibody was prepared by repeated immunizations with an Erk2 containing fusion protein.  The epitope maps near the carboxy-terminus of human p42 MAP Kinase (ERK2) protein.  The epitope is identical to the corresponding sequence in mouse and differs from the rat sequence by a single, conservative amino acid substitution.
This antiserum is directed against human p42 MAP Kinase (ERK2) protein and is useful in determining its presence by immunoblotting.  No reactivity is observed against p44 MAP Kinase (ERK1).  Cross reactivity is expected with p44 MAP Kinase (ERK1) proteins from human and mouse sources.  Reactivity to rat tissues is also anticipated due to high sequence homology.  Reactivity against homologues from other sources is not known.

Application Details

This antiserum was tested for use in ELISA and by western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a predominant band approximately 42 kDa in size corresponding to p42 MAP Kinase (ERK2) by western blotting in the appropriate cell lysate or extract.  p42 MAP Kinase (ERK2) is a ubiquitous protein kinase target for Ras and Raf.  The following cell lines have been assayed by immunoblot and were found to be positive for p42 MAP Kinase (ERK2) using this reagent:  U937, HeLa,  NIH-3T3, RAW 264.7, LNCaP and HEK whole cell lysates.
