Product Name:
ERK5-pT219
Product Number:
ab-pk968
Target Full Name: Extracellular regulated protein-serine kinase 5 (Big MAP kinase 1 (BMK1))
Product Type Specific: ERK5 protein kinase phosphosite-specific antibody
Antibody Code: PK968
Antibody Target Type: Phosphosite-specific
Antibody Phosphosite: T219
Protein UniProt: Q13164
Protein SigNET: ERK5
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Synthetic phosphopeptide patterned after human ERK5
Antibody Immunogen Sequence: QYFM(pT)E(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues Q215 to E220.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: ERK5 (MAPK7) is a 98 kDa protein-serine/threonine kinase of the CMGC group and MAPK family. It is important in controlling a cell's proliferation, differentiation, and. survival, and angiogenesis. Phosphorylation of T219 and Y221 in a 'TEY" motif by MEK5 (MAP2K5) increases the phosphotransferase activity of ERK5. MEK5 is activated in response to hyperosmolarity, hydrogen peroxide, and epidermal growth factor (EGF). While ERK5 exists in both the cytoplasm and nucleus, its activation often induces translocation to the nucleus, where it activates transcription factors such as MEF2C and c-Myc. MEF2A/C/D, connexin-43 and SGK1 are also substrates for ERK5. It is highly expressed in heart, skeletal muscle, vascular endothelium, and the nervous system. ERK5 may be a tumour requiring protein (TRP). Although there has been no direct linkage of ERK5 to formation of carcinomas in humans in vivo, in vitro, ERK5 over-expression has been shown to increase metastasis, and ERK5 inhibition has been shown to inhibit osteosarcoma cell motility. Upregulation of the MEK5 gene has been noted in breast, prostate, and liver cancer. This description may include information annotated by UniProt and/or Google AI.
