CC   -!- FUNCTION: SRF is a transcription factor that binds to the serum
CC       response element (SRE), a short sequence of dyad symmetry located 300
CC       bp to the 5' of the site of transcription initiation of some genes
CC       (such as FOS). Together with MRTFA transcription coactivator, controls
CC       expression of genes regulating the cytoskeleton during development,
CC       morphogenesis and cell migration. {ECO:0000250|UniProtKB:Q9JM73}.
CC   -!- SUBUNIT: Binds DNA as a multimer, probably a dimer.
CC       {ECO:0000250|UniProtKB:Q9JM73}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9JM73,
CC       ECO:0000255|PROSITE-ProRule:PRU00251}.
