Reading frame maintenance is a critical property of ribosomes. However, a number of genetic elements have been described that can induce ribosomes to shift on mRNAs, the most well understood of which are a class that directs ribosomal slippage by one base in 5' (-1) direction. This is referred to as programmed -1 ribosomal frameshifting (-1 PRF). Recently, a new -1 PRF promoting element was serendipitously discovered in a study examining the effects of stretches of adenosines in the coding sequences of mRNAs. Here, we discuss this finding, recent studies describing how -1 PRF is used to control gene expression in eukaryotes, and how -1 PRF is itself regulated. The implications of dysregulation of -1 PRF on human health are examined, as are possible new areas in which novel -1 PRF promoting elements might be discovered. Also watch the Video Abstract.
