Antibody Host Species: Rabbit
Antibody Immunogen Source: Human p38d MAPK (MAPK13) sequence peptide Cat. No.: PE-04ADU85
Antibody Immunogen Sequence: AEM(pT)G(pY)(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues A177 to Y182; In the protein kinase catalytic domain activation T loop region between subdomains VII and VIII.
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.This antibody was also subject to negative purification over phosphotyrosine-agarose.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: p38d (MAPK13) is a protein-serine/threonine kinase of the CMGC group and MAPK family. It is essential for MAP kinase signalling that can be induced via physical stress or proinflammatory cytokines. It is activated by phosphorylation at Y182 and probably T180 by (MKK3 (MAP2K3) and MKK6 (MAP2K6). p38d signalling can be induced via physical stress or proinflammatory cytokines resulting in the activation of the transcription factors ELK1 and ATF2. It can affect proliferation, differentiation, transcription regulation, translation regulation, cytoskeleton regulation, insulin secretion, cell survival and development. p38d can be a positive or negative regulator of the above processes depending on the cell context. Increased expression of p38d has been associated with increases proliferation and metastatic progression. It is also hypermethylated in some cancer cell lines. The rare liver cancer Cholangiocarcinoma (CCA, CC) has been noted to have a significant up-regulation of p38d compared to normal bile duct tissue. Insulin secretion and pancreatic beta cell survival can be regulated by p38d.
