Phosphorylation of Serum Response Factor, a Factor that Binds to the Serum Response Element of the c-FOS Enhancer

Serum and growth factor regulation of c-FOS protooncogene transcription is mediated by the serum response element. A factor, serum response factor, binding to this element has already been identified. We demonstrate that serum response factor is phosphorylated in vivo on serine residues and that pho...
