| Title | Dominant Negative PDE4 constructs |
| Description | A single point mutation in the active site was first made to catalytically inactive a particular PDE4 isoform. Overexpression of this in cells would 'replace' the tethered cognate form at a particular site in a cell, thereby increasing localized cAMP levels around this specific site, with a defined phenotypic output. This, effectively, inhibits a specific isoform at a specific site. |
| Type Of Material | Technology assay or reagent |
| Year Produced | 2006 |
| Provided To Others? | Yes |
| Impact | We used these novel reagents to great effect in altering people's perception of the functioning of PDE4 isoforms by showing that (i) the tethering of specific isoforms was critical to phenotypic function and that (ii) isoforms had non-redundant roles in cells that depended upon their targeting. Provides proof of principal of a novel therapeutic approach based upon displacing specific PDE4 isoforms from specific sites in cells with much reduced side effects. Extremely beneficial collaborations resulted from sharing these that have greatly aided our research. |
