Light causes phosphorylation of nonactivated visual pigments in intact mouse rod photoreceptor cells.

Phosphorylation of G-protein-coupled receptors (GPCRs) is a required step in signal deactivation. Rhodopsin, a prototypical GPCR, exhibits high gain phosphorylation in vitro whereby a hundred-fold molar excess of phosphates are incorporated into the rhodopsin pool per molecule of activated rhodopsin. The extent by which high gain phosphorylation occurs in the intact mammalian photoreceptor cell...

Changes in the visual pigments of trout.

ALLEN, D. M., W. N. MCFARLAND, F. W. MUNZ, and H. A. Pos-roN. 1973. Changes in the visual pigments of trout. Can. J. Zool. 51: 901-914. The proportions of two visual pigments (rhodopsin and porphyropsin) were examined in four species of trout under experimental and natural conditions. Brook trout (Salvelinus fontinalis), rainbow trout (Santo gairdneri), and brown trout (Salmo truita) have diffe...

The visual pigments of a deep-sea teleost, the pearl eye Scopelarchus analis.

The eyes of deep-sea fish have evolved to function under vastly reduced light conditions compared to those that inhabit surface waters. This has led to a bathochromatic shift in the spectral location of maximum absorbance (lambda(max)) of their rod (RH1) pigments and the loss of cone photoreceptors. There are exceptions to this, however, as demonstrated by the deep-sea pearl eye Scopelarchus an...
