Atkins group
Professor John F. Atkins
About the Atkins recoding research group
Codes with THE code. Signals buried within the coding sequence of a minority of mRNAs in probably all organisms stimulate a non-standard decoding event utilized for gene expression purposes. The non-standard event can be local redefinition of codon meaning, a shift of reading register or the bypassing of a block of nucleotides present in the mature mRNA. The efficiency of some of the "recoding" events is responsive to the cellular level of a component, such as polyamines or release factor 2, and these events can serve an autoregulatory function. In others there is a fixed ratio of the product of standard decoding to that of the recoding product which serves some unique function.
We are investigating the occurrence, mechanisms involved and the functions of recoding. In addition to seeking basic understanding, we are also using the potential to manipulate recoding and related aspects of protein synthesis for societal beneficial purposes. In that regards we are seeking small molecule inhibitors of Foot and Mouth Disease propagation via targeting an unusual form of recoding required for viral expression but is not utilized by viral hosts.
In 2012 together with collaborators elsewhere we discovered that the pig pathogen Porcine Reproductive and Respiratory Syndrome Virus and other arteriviruses utilize a different form of recoding, programmed -2 frameshifting, that is a potentially useful antiviral target and are searching for other novel recoding-based targets.
We are also investigating the nature of the recoding required for synthesis in mammals of the selenium transport protein and starting to employ the reagents being generated for clinical purposes. We are keen to exploit knowledge gained from recoding and related studies for the amelioration of genetic disease, to optimize protein synthesis under particular over-expression situations.
