Overexpression of Protor-2 promotes TTP-associated mRNA turnover. A. Expression of myc-tagged Protor-2 in Jurkat cells. Lane 1, JurkatPuro control transfectants, Lane 2, JurkatProtor2 overexpression clone. Western blot was probed with a-myc epotope antibodies (4E11) and actin. B. Relative mRNA turnover and half-lives (t1/2) of the indicated transcripts from JurkatPuro (shaded circles) or JurkatProtor2 (shaded squares) as determined by ActD-mRNA half-life experiments followed by real time qRT-PCR of the indicated transcripts. C. Relative mRNA turnover of the indicated mRNAs in JurkatZeo (open circles) versus TSCsiJurkat (shaded triangles) cells following tet-induced suppression of TSC1/TSC2.
