Alt-P3 may promote but is not essential for active telomerase assembly in in cells. (A) Activity assay, (B) immunoblot and (C) northern blot to follow assembly and activity of P3 duplex-swap hTRmin mutations co-expressed with ZZF-tagged TERT in U20S cells, paralleling the experiments described in Figure 5. Values for rRAP* and rAct were calculated as described in Figure 3. Similar results were obtained from two independent experimental replicates.
