  • 功能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.
  • 组织特异性Lung and testis.
  • 序列相似性Belongs to the ETS family.
    Contains 1 ETS DNA-binding domain.
  • 翻译后修饰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. Phosphorylation leads to loss of sumoylation and restores transcriptional activator activity.

Anti-ELK1 (phospho S389) antibody 图像

  • Immunohistochemical analysis of paraffin-embedded breast carcinoma. Left: Using Phospho-ELK-1(Ser389) ab28818; Right: The same antibody preincubated with synthesized phosphopeptide.
  • ab28818 staining ELK1 (phospho S389) in human bladder transitional cell carcinoma tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde; antigen retrieval was by heat mediation with a citrate buffer. Samples were incubated with primary antibody (1/50) for 1 hour at 20°C. An undiluted HRP-conjugated Mouse anti-rabbit polyclonal was used as the secondary antibody.
