CAT#: TA389129

Anti-ERK1 (Thr-202/Tyr-204) [conserved], Phosphospecific Antibody

Specifications

Product Data

• Clone Name: M206
• Applications: ICC, WB
• Recommended Dilution: WB: 1:1000
  ICC: 1:100
• Reactivities: Human, Rat, Mouse
• Host: Mouse
• Isotype: IgG1
• Immunogen: Clone M206 was generated from a dual phosphorylated ERK1 (Thr-202/Tyr-204) synthetic peptide (coupled to carrier protein) corresponding to amino acids surrounding Thr-202 and Tyr-204 in human ERK1. This sequence is conserved in rat and mouse ERK1, and is highly conserved in ERK2.
• Specificity: The antibody detects 42 and 44 kDa* proteins corresponding to ERK1 and ERK2 on SDS-PAGE immunoblots of human A431 epithelial cells stimulated with EGF or calyculin A. It does not detect bands in control cells.
• Formulation: PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol
• Concentration: lot specific
• Purification: Protein A Purified
• Conjugation: Unconjugated
• Storage: Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
• Stability: After date of receipt, stable for at least 1 year at -20°C.
• Predicted Protein Size: 42/44
• Database Link:
  UniProt ID P28482
• 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 ERK1/2 (p44/42) signaling pathway can be activated in response to a diverse range of extracellular stimuli including mitogens, growth factors, and cytokines. Upon stimulation, a sequential three-part protein kinase cascade is initiated, consisting of a MAP kinase kinase kinase (MAPKKK), a MAP kinase kinase (MAPKK), and a MAP kinase (MAPK). Multiple ERK1/2 MAPKKKs 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. MEK1 and MEK2 activate ERK1 and ERK2 through phosphorylation of activation loop residues Thr-202/Tyr-204 and Thr-185/Tyr-187, respectively. ERK1/2 are negatively regulated by a family of dual-specificity (Thr/Tyr) MAPK phosphatases. Several downstream targets of ERK1/2 have been identified, including p90RSK and the transcription factor Elk-1.
