The exceptions to standard decoding provide us with insights that contribute to our understanding of standard decoding but they are also important in their own right. Recoding is widely used by viruses, especially plant viruses, and current work is revealing the critical setting of this phenomenon in retroviruses and identifying new regulatory control points.

In decoding the information in some genes to yield their protein products, the standard readout rules are transitorily over-ridden – the phenomenon of recoding. In one type of recoding a proportion of the readout machinery changes reading register resulting in an extra product as well as that derived from standard decoding. Examples include proteins that are essential for HIV and the SARS causing viruses. Another example serves a sensor and effector of regulatory circuit that governs the level of polyamines. In humans their level is critical for the prevention of certain disease states including cancer and we have been studying analogs with a view to intervention. In yet another case an extensive region of coding sequence is translationally bypassed and its study is providing a novel portal for insights to the functioning of the readout machinery.

A different type of recoding is where the meaning of a coding unit is dynamically changed when it occurs at specific locations. We have found the contextual signals that cause a “stop” in a mammalian virus to instead allow the readout machinery to continue protein synthesis We are actively pursuing the type of “meaning redefinition” utilized by Foot and Mouth disease virus as it appears that its hosts do not use the same mechanism and it could be a target for small molecule intervention.

Though the readout machinery is dependent on proteins for it speed and accuracy, its central functions are mediated by RNA. More broadly, we are alert to the possibility that studies of the readout machinery may provide new clues as to how the process got started in the first place. Not only does RNA play a central role in the readout machinery, it is being found to play unexpectedly diverse roles in the functioning of human and other cells. These roles, and where appropriate their evolutionary implications, are the topic of a recent book co-edited with Ray Gesteland and Tom Cech.
