Description

General description

Mitogen-activated protein kinase 3 (ERK1) is mapped to human chromosome 16p11.2. It has a serine/threonine domain and a transactivation domain (TAD) and a nuclear localization sequence (NLS).

Immunogen

synthetic peptide corresponding to amino acids 351-368 of human ERK-1.

Application

Anti-MAP Kinase (ERK-1, 351-368) antibody produced in rabbit has been used in:

• immunofluorescence
• immunoprecipitation
• western blotting.

Biochem/physiol Actions

By immunoblotting, the antibody reacts with ERK-1 and ERK-2.

Mitogen-activated protein kinase (MAPK) superfamily of enzymes is involved in widespread signalling pathways. Members of this family include the ERK1/2 (extracellular signal-regulated protein kinase, also termed p42/p44 MAPK), c-Jun N-terminal kinases (JNK) and p38 MAPK subfamilies. These are the terminal enzymes in a signalling cascade where each kinase phosphorylates and activates the next member in the sequence. Phosphorylation of both tyrosine and threonine is essential for the full activation of all MAPKs. Several kinases participate in activation of the ERK cascade. This cascade is initiated by the small G protein Ras, which upon stimulation causes activation Raf1 kinase. Raf1 continues the transmission by activating MEK. Activated MEK appears to be the only kinase capable of specifically phosphorylating and activating ERK. ERK1 (p44) and ERK2 (p42) require the dual phosphorylation in the catalytic kinase domain by MEKs for their full activity. ERK1 is phosphorylated on Tyr204 and Thr202, and ERK2 on Tyr187 and Thr185. ERK1 and 2 may also undergo autophosphorylation on these residues. ERK appears to be an important regulatory molecule, which by can phosphorylate regulatory targets in the cytosol (phospholipase A2, PLA2), translocated into and phosphorylate substrates in the nucleus (ELK1). The activation of ERK cascade mediates and regulates the signal transduction pathways in response to stress, mitogenic signals and is important in development and differentiation, learning, memory and survival.
