Intact PKG1 β is required for activation of gene expression. A) Schematic representations are shown of full length PKG1β (pCMV-PKG1β FLAG) and two deletion mutants, pCMV-PKG1β 1–417 FLAG and pCMV-PKG1β Δ349FLAG. Transfected cell lysates (right panel) were analyzed by Western blotting using anti-FLAG antibody for expression. B) Full length PKG1β, but not its deletion mutants, activated LTR-luciferase expression. HeLa cells were transfected with the indicated plasmids. C) Full PKG1β, but not its deletion mutants, activated pNL4-3-expression. Plasmids were transfected into HeLa cells as indicated. C- and N-terminus deletions of PKG1β resulted in loss of activity.
