| Specificity / Sensitivity | p44/42 MAPK (Erk1/2) (3A7) Mouse mAb detects endogenous levels of total p44/42 MAP kinase (Erk1/2). It does not cross-react with either JNK/SAPK or p38 MAP kinase. |
| Source / Purification | Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the sequence of p44/42 MAP kinase. Western Blotting
Western blot analysis of extracts from COS cells, untreated or treated with either U0126 #9903 (10 µM for 1h) or TPA #9905 (200 nM for 10 m), using Phospho-p44/42 MAPK (Erk1/2) (Thr202/Tyr204) (D13.14.4E) Rabbit mAb #4370 and p44/42 MAPK (Erk1/2) (3A7) Mouse mAb #9107. Western Blotting
Western blot analysis of extracts from various cells, using p44/42 MAPK (Erk1/2) (3A7) Mouse mAb. |
| Background | Mitogen-activated protein kinases (MAPKs) are a widely conserved family of serine/threonine protein kinases involved in many cellular programs such as cell proliferation, differentiation, motility, and death. The p44/42 MAPK (Erk1/2) signaling pathway can be activated in response to a diverse range of extracellular stimuli including mitogens, growth factors, and cytokines (1-3) and is an important target in the diagnosis and treatment of cancer (4). Upon stimulation, a sequential three-part protein kinase cascade is initiated, consisting of a MAP kinase kinase kinase (MAPKKK or MAP3K), a MAP kinase kinase (MAPKK or MAP2K), and a MAP kinase (MAPK). Multiple p44/42 MAP3Ks have been identified, including members of the Raf family, as well as Mos and Tpl2/Cot. MEK1 and MEK2 are the primary MAPKKs in this pathway (5,6). MEK1 and MEK2 activate p44 and p42 through phosphorylation of activation loop residues Thr202/Tyr204 and Thr185/Tyr187, respectively. Several downstream targets of p44/42 have been identified, including p90RSK (7) and the transcription factor Elk-1 (8,9). p44/42 are negatively regulated by a family of dual-specificity (Thr/Tyr) MAPK phosphatases, known as DUSPs or MKPs (10), along with MEK inhibitors such as U0126 and PD98059.

Study of MAPK Signaling Using Knockout Mice
The p42 and p44 mitogen-activated protein kinases (MAPKs) (p42/p44 MAPK, Erk2 /Erk1) are activated through the small G protein Ras and sequential activation of the protein kinases Raf and MEK on stimulation of cells with a broad range
Lentiviral Vectors to Study the Differential Function of ERK1 and ERK2 MAP Kinases
Accumulating evidence indicates that p44ERK1 and p42ERK2 mitogen-activated protein kinases (MAPKs) have distinct quantitative roles in cell signaling. In our recently proposed model of regulation of ERK1 and ERK2, p42 plays a major role
