Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Species predicted to react based on 100% sequence homology: Human, Mouse, Rat, Monkey, Zebrafish, Dog.
Specificity / Sensitivity
Phospho-Elk-1 (Ser383) Antibody detects less than 5 ng of recombinant phosphorylated Elk-1, and will not react with up to 1 µg of recombinant nonphosphorylated EIk-1 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues around Ser383 of human Elk-1. Antibodies are purified by protein A and peptide affinity chromatography.
The transcription factor Elk-1 is a component of the ternary complex that binds the serum response element (SRE) and mediates gene activity in response to serum and growth factors (1-3). Elk-1 is phosphorylated by MAP kinase pathways at a cluster of S/T motifs at its carboxy terminus; phosphorylation at these sites, particularly Ser383, is critical for transcriptional activation by Elk-1. Elk-1 appears to be a direct target of activated MAP kinase: (a) biochemical studies indicate that Elk-1 is a good substrate for MAP kinase; (b) the kinetics of Elk-1 phosphorylation and activation correlate with MAP kinase activity; (c) interfering mutants of MAP kinase block Elk-1 activation in vivo. Other studies have shown that Elk-1 (Ser383) is also a target of the stress-activated kinase SAPK/JNK (4,5).
