General description

Monoclonal Anti-MAP Kinase, Mono-phosphorylated Tyrosine (pY-ERK) (mouse IgG1 isotype) is derived from the ERK-PY193 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide sequence corresponding to the phosphorylated form of ERK-activation loop, conjugated to KLH. The mitogen-activated protein kinase (MAPK) superfamily of enzymes is involved in many signaling pathways. This family includes the ERK1/2 (extracellular signal-regulated protein kinase, also termed p42/p44 MAPK), JNK (c-Jun N-terminal protein kinase, also termed stress-activated protein kinase, SAPK1), and p38 MAPK (also termed SAPK2) subfamilies.


The antibody reacts with the monophosphorylated tyrosine form of MAP kinases (ERK1 and ERK2). It does not recognize the non-phosphorylated, diphosphorylated, and the monophosphorylated threonine forms of ERK/MAP kinases, or the diphosphorylated forms of JNK and p38 MAPK. The epitope recognized by the antibody contains the phosphorylated tyrosine residue within the regulatory site of MAP kinase (e.g.,Tyr185 in ERK-2). Cross-reactivity has been observed with the monophosphorylated tyrosine peptide of JNK.


synthetic peptide HTGFLTEpYVAT, corresponding to the phosphorylated form of ERK-activation loop.

Biochem/physiol Actions

MAPK kinase (MAPKK) is the immediate upstream activator of the MAPK, MAPKK kinase (MAP3K), and MAP3K kinase (MAP4K) for the enzymes further upstream, respectively. The kinases in the MAPK level are activated by phosphorylation of both tyrosine (Y) and threonine (T) residues organized in a TXY motif. The residue in between the two phosphorylated residues determines the specificity of activation of the MAPKs. Phosphorylation of both tyrosine and threonine is essential for the full activation of all MAPKs.

Preparation Note

Prepared from a culture supernatant of bioreactor grown hybridoma.
