Abstract:
In vitro translation is a powerful method for specifically investigating mRNA translation independently of transcription, post-translational processing, and protein trafficking. There are several well-characterized in vitro translation systems including mammalian cell extracts (e.g., HeLa cells and Chinese Hamster Ovary cells) (1,2), rabbit reticulocyte lysates (3,4), Xenopus egg extracts (5), rye embryo (6), and wheat germ (7,8) that efficiently and faithfully translate heterologous mRNAs. Our laboratory is interested in investigating translational control of the angiotensin AT(1) receptor. Thus, we need a cell-free system that efficiently translates the angiotensin AT(1) receptor.

Initiation of Translation
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...
