Descripción

General description

Erk (Extracellular signal-Related Kinase) is a family of two, highly homologous proteins denoted as Erk1 (p44, MAPK3) and Erk2 (p42, MAPK1) that both function in the same pathway. The two proteins are often referred to collectively as ERK1/2 or p44/p42 MAP kinase. The Erk pathway is considered the classical, canonical MAPK (Mitogen-Activated Protein Kinase) signaling pathway. It is an evolutionarily conserved pathway that controls and is a critical regulator the growth and survival through the promotion of cell proliferation and the prevention of apoptosis. Erk is involved in the control of many fundamental cellular processes including cell proliferation, survival, differentiation, apoptosis, motility and metabolism. Erk is activated by growth factor stimulation of receptor tyrosine kinases (RTKs) and/or integrin stimulation. This activates the Ras-Raf-MEK,-Erk pathway that results in MEK, a dual kinase (a Ser/Thr and a Tyr kinase), phosphorylation and activation of ERK1/2 (p44/044) on the TxY motif (Thr202/Tyr204 and Thr185/Tyr187 for Erk1 and Erk2, respectively).

Specificity

Predicted to cross-react with many species based on sequence homology.

Recognizes phosphorylated MAP Kinase 1 and 2 (Erk 1&2).

Immunogen

KLH-conjugated, synthetic peptide corresponding to amino acids surrounding the pTEpY motif of human phospho-MAP Kinase 1/2 (Erk1/2), in which the Thr and Tyr residues are phosphorylated. The immunizing sequence is highly conserved among species.
