SRF [ENSP00000265354]
 
serum response factor (c-fos serum response element-binding transcription factor); SRF is a transcription factor that binds to the serum response element (SRE), a short sequence of dyad symmetry located 300 bp to the 5' of the site of transcription initiation of some genes (such as FOS). Required for cardiac differentiation and maturation
