Serum Response Factor SRF Lysates

Serum response factor (SRF) is a transcription factor that binds the serum response element (SRE), a sequence that mediates the transient response of many cellular genes to growth stimulation. SRF is a cardiac-enriched transcription factor that is required for the appearance of beating sarcomeres in the heart. In addition, SRF may also direct the expression of microRNAs that inhibit the expression of cardiac regulatory factors. SRF binding sites are also constitutive promotor elements in many ...
