Target Information
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. It is phosphorylated by MAP kinase pathways at a cluster of serine/threonine motifs at its C-terminus. Phosphorylation at these sites, particularly Ser383, is critical for transcriptional activation by ELK1. ELK1 acts as a direct target of activated MAP kinase and serves as a nuclear effector in the ras-raf-MAPK signaling cascade. Alternatively spliced transcript variants encoding the same protein have been identified.
