BIOCHEMISTRY Retraction for “Two RNA subunits and POT1a are components of Arabidopsis telomerase,” by Catherine Cifuentes-Rojas, Kalpana Kannan, Lin Tseng, and Dorothy E. Shippen, which was first published December 16, 2010; 10.1073/pnas.1013021107 (Proc. Natl. Acad. Sci. U.S.A. 108, 73–78).
The authors wish to note the following: “It has come to our attention that the RNA molecule we identified in our publication as a telomerase component for the Arabidopsis thaliana is incorrect, and is likely to be a contaminating mRNA species that copurified with enzyme activity. Subsequent work by our laboratory (1) and others (2) has definitively identified the authentic RNA subunit of the A. thaliana telomerase. We hereby retract the article and sincerely regret any inconvenience this error has caused.”
