Star-PAP S6 phosphorylation together with PIPKIα determines specificity of target mRNA expression. qRT-PCR analysis of (A) Star-PAP target mRNAs as indicated with total RNA isolated from HEK 293 cells after Star-PAP knockdown rescued with stable expression of WT or S6A mutant Star-PAP; (B) after knockdown of PIPKIα or Star-PAP; (C) qRT-PCR as in (A) with select Star-PAP target mRNAs as indicated and (D) more Star-PAP target mRNAs as in (A) to screen for S6-phospho dependent target mRNAs. (E) Western blot analysis showing knockdowns of Star-PAP and PIPKIα. Wherever siRNA (−) is indicated in the figure, we have used control scrambled siRNA.
