  • Elk-1
  • ELK1, member of ETS oncogene family
  • ETS domain-containing protein Elk-1
  • ETS-like gene 1


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. The serum reponse element in the promoter of the c-fos proto-oncogene. 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. Elk-1 is a member of the Ets family of transcription factors (TCF) subfamily. The protein encoded by this gene is a nuclear target for the ras-raf-MAPK signaling cascade. lternatively spliced transcript variants encoding the same protein have been found for this gene.
