Two visual pigments in a single photoreceptor cell: identification and histological localization of three mRNAs encoding visual pigment opsins in the retina of the butterfly Papilio xuthus.
Most mammals have two spectral cone types containing either of two visual pigments (opsins), one sensitive to shortwave light (UV/blue opsin), and the other to middle-to-longwave light (green opsin).
The raw pre- and post-bleach difference spectra were averaged and fitted with a visual pigment template curve based on the equations of Stavenga et al.
Vision in stomatopods and other animals requires light-sensitive visual pigments, composed of a chromophore bound to an opsin protein, to initiate the phototransduction cascade.
The visual pigments of zooplankton are understood to absorb light that controls, initiates, and often orients DVM behavior (Forward, 1988).
The RPE cells perform several functions, including absorption of light, enabling the turnover of photoreceptor outer segments, formation of visual pigments by storing and releasing vitamin A.
Normally, biochemists need concentrated extracts from some 50 to 100 shrimp in order to detect any visual pigment molecules, says Szuts.
If a retinula cell possesses a visual pigment, the absorption of the long wavelength quanta has the same effect on a receptor as the absorption of a short wavelength quanta (the principle of univariance; Naka and Rushton, 1966).
The researchers think this will allow them to capture changes in such molecules as hemoglobin as it binds to oxygen or the visual pigment rhodopsin when it is struck by light.
Templates for A1-based visual pigment (rhodopsin) absorbance (Govardovskii et al., 2000) were used to calculate the absorptance curve that produced a minimum sum of squares fit to the spectral sensitivity data (Stavenga et al., 1993).
Nathans and his colleagues first used a gene that had already been identified as that of the bovine visual pigment called rhodopsin.
In addition, certain species with only one visual pigment have multibanked retinas.
Each of these contains a different visual pigment (Cronin and Marshall, 1989a, b), producing eight distinct classes of spectral receptor.
Microspectrophotometric measurements on single photoreceptors revealed only a single visual pigment with peak absorbance at 495 nm in the blue-green region of the spectrum.
