:
DDAH2 transfection increased nuclear and threonine-phosphorylation levels of Sp1 in a protein kinase A (PKA) dependent manner ... DDAH2 increased Sp1 DNA binding activity was PKA dependent
Barclay et al., Int J Cancer 2009
(Breast Neoplasms) :
In addition, prolactin induced SOCS3 promoter activation requires PKA stimulated Sp1 binding to the GC-rich region of the promoter
Rohlff et al., J Biol Chem 1997
:
Reporter gene activity under the control of the Sp1 dependent SV40 promoter is stimulated in insect cells transiently expressing Sp1 and PKA, and the DNA binding activity of recombinant Sp1 is activated by exogenous PKA in vitro
