Detergent-resistant membrane microdomains in the plasma membrane, known as lipid rafts, have been implicated in various cellular processes. We report here that a low-density Triton X-100-insoluble(More)
Cyclic GMP phosphodiesterase (PDE) is an essential component in retinal phototransduction. PDE is regulated by Pgamma, the regulatory subunit of PDE, and GTP/Talpha, the GTP-bound alpha subunit of(More)
Interaction between the gamma subunit (Pgamma) of cGMP phosphodiesterase and the alpha subunit (Talpha) of transducin is a key step for the regulation of cGMP phosphodiesterase in retinal rod outer(More)
Delta(1)-Pyrroline-5-carboxylate reductase (P5CR) (EC 1.5.1.2. L-proline: NAD(P)-5-oxidoreductase), the second enzyme in the proline biosynthetic pathway, was purified from spinach (Spinacia oleracea(More)
