Phosphorylation influences DNA binding and transactivator capabilities of multiple transcription factors. In this study, we demonstrate that the POU-domain transcription factor, Oct-3, can be phosphorylated in vivo. In addition, we show that in COS-1 cells Oct-3 is phosphorylated exclusively on serine residues. Lastly, we provide evidence that phosphorylation is not required for Oct-3 binding to DNA and treatment of Oct-3 with calf intestinal alkaline phosphatase does not influence its ability to bind DNA.
