Cancer antibody; Gene Regulation antibody; Signaling Transduction antibody
|Product Description||Rabbit Polyclonal antibody recognizes ELK1 phospho (Ser389)|
|Tested Reactivity||Hu, Ms, Rat|
|Tested Application||IHC-P, WB|
|Immunogen||Peptide sequence around phosphorylation site of serine 389 (P-R-S(p)-P-A) derived from Human Elk-1.|
|Alternate Names||ETS domain-containing protein Elk-1|
|Application Note||* The dilutions indicate recommended starting dilutions and the optimal dilutions or concentrations should be determined by the scientist.|
|Purification||Antibodies were produced by immunizing rabbits with KLH-conjugated synthetic phosphopeptide. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. In addition, non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.|
|Buffer||PBS (without Mg2+ and Ca2+, pH 7.4), 150mM NaCl, 0.02% Sodium azide and 50% Glycerol.|
|Preservative||0.02% Sodium azide|
|Storage Instruction||For continuous use, store undiluted antibody at 2-8°C for up to a week. For long-term storage, aliquot and store at -20°C. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening. The antibody solution should be gently mixed before use.|
|Note||For laboratory research only, not for drug, diagnostic or other use.|
|Gene Full Name||ELK1, member of ETS oncogene family|
|Background||Elk-1 is a member of the Ets family of transcription factors and of the ternary complex factor (TCF) subfamily. Proteins of the TCF subfamily form a ternary complex by binding to the the serum response factor and the serum reponse element in the promoter of the c-fos proto-oncogene. The protein encoded by this gene is a nuclear target for the ras-raf-MAPK signaling cascade. Alternatively spliced transcript variants encoding the same protein have been found for this gene|
|Function||Stimulates transcription. Binds to purine-rich DNA sequences. Can form a ternary complex with the serum response factor and the ETS and SRF motifs of the fos serum response element. [UniProt]|
|Research Area||Cancer antibody; Gene Regulation antibody; Signaling Transduction antibody|
|Calculated MW||45 kDa|
|PTM||Sumoylation represses transcriptional activator activity as it results in recruitment of HDAC2 to target gene promoters which leads to decreased histone acetylation and reduced transactivator activity. It also regulates nuclear retention.
On mitogenic stimulation, phosphorylated on C-terminal serine and threonine residues by MAPK1. Ser-383 and Ser-389 are the preferred sites for MAPK1. In vitro, phosphorylation by MAPK1 potentiates ternary complex formation with the serum responses factors, SRE and SRF. Also phosphorylated on Ser-383 by MAPK8 and/or MAKP9. Phosphorylation leads to loss of sumoylation and restores transcriptional activator activity. Phosphorylated and activated by CAMK4, MAPK11, MAPK12 and MAPK14. Upon bFGF stimulus, phosphorylated by PAK1 (By similarity).
