The carboxyl-terminal transcription activation domain was mapped within a 71-amino acid region that contains both DNA-PK phosphorylation sites. Amino acid substitutions that interfered with phosphorylation by DNA-PK at Ser-435/446 in GAL4-SRF fusion proteins were reduced in transactivation potency. From these data we suggest that DNA-PK phosphorylation may modulate SRF activity in vivo. |
