Sp1 dephosphorylation is likely to increase its transcriptional activity because PP2A overexpression potentiated Sp1 site-driven chloramphenicol acetyltransferase expression in dividing Kit225 T cells and okadaic acid reversed this effect

:
These results suggest that lyso-PC up-regulates eNOS transcription by a PP2A dependent increase in Sp1 binding activity
