Rhodopsin phosphorylation suggests biochemical heterogeneities of retinal rod disks.


Frogs (Rana pipiens) were injected subcutaneously with (3H)-leucine and allowed to incorporate the radioactive amino acid into newly assembled disks in the retinal rod outer segment. The labeled disks served as a temporal marker for following the turnover of rod outer segments. Animals were killed at different times after injection and outer segments were… (More)
