Baehr, Wolfgang; Prestwich, Glenn D. | Photoreceptor cGMP phosphodiesterase delta subunit (PDEdelta) functions as a prenyl-binding protein | Bovine PDEdelta was originally copurified with rod cGMP phosphodiesterase (PDE) and shown to interact with prenylated, carboxymethylated C-terminal Cys residues. Other studies showed that PDEdelta can interact with several small GTPases including Rab13, Ras, Rap, and Rho6, all of which are prenylate... | Fluorescence Resonance Energy Transfer; GTP Phosphohydrolases; Immunohistochemistry | 2004 |

Baehr, Wolfgang | Role of photoreceptor-specific retinol dehyrogenase (prRDH) in the retinoid cycle in vivo | The retinoid cycle is a recycling system that replenishes the 11-cis-retinal chromophore of rhodopsin and cone pigments. Photoreceptor-specific retinol dehydrogenase (prRDH) catalyzes reduction of all-trans-retinal to all-trans-retinol and is thought to be a key enzyme in the retinoid cycle.
