ELK1 pSer389 Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	IHC
Recommend Dilution	Suitable for use in Immunohistochemistry (1:50~1:100).
Reactivity	Human
Host	Rabbit
Clonality	Polyclonal
Immunogen	The antiserum was produced against synthesized phosphopeptide derived from human Elk-1 around the phosphorylation site of serine 389 (P-R-SP-P-A).
Specificity	The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site. Elk-1 (phospho-Ser389) antibody detects endogenous levels of Elk-1 only when phosphorylated at serine 389.
Formulation	Phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150 mM NaCl, 0.02% Sodium Azide and 50% glycerol. State: Aff - Purified State: Liquid purified Ig fraction.
Concentration	lot specific
Purification	Immunoaffinity chromatography.
Conjugation	Unconjugated
Storage Condition	Store the antibody (in aliquots) at -20°C. Avoid repeated freezing and thawing.
Gene Name	ELK1, ETS transcription factor
Database Link	Entrez Gene 2002 Human UniProt ID P19419
Background	The transcription factor Elk1 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. Elk1 is phosphorylated by MAP kinase pathways at a cluster of S/T motifs at its C terminus. Phosphorylation at these sites, particularly Ser383, is critical for transcriptional activation by Elk1. Elk1 appears to be a direct target of activated MAP kinase. Biochemical studies indicate that Elk1 is a good substrate for MAP kinase, the kinetics of Elk1 phosphorylation and activation correlate with MAP kinase activity, and interfering mutants of MAP kinase block Elk1 activation in vivo. More recent studies have shown that Elk1 (Ser383) is also a target of the Stress Activated Kinase SAPK/JNK. Phosphorylation of Elk1 has also been implicated in synaptic plasticity in the adult hippocampus.
Synonyms	Elk-1
