Spectral-tuning mechanisms of marine mammal rhodopsins and correlations with foraging depth
It has been observed that deep-foraging marine mammals have visual pigments that are blue shifted in terms of their wavelength of maximal absorbance (λmax) when compared to analogous pigments from terrestrial mammals. The mechanisms underlying the spectral tuning of two of these blue-shifted pigment...

| description | It has been observed that deep-foraging marine mammals
have visual pigments that are blue shifted in terms of
their wavelength of maximal absorbance (λmax)
when compared to analogous pigments from terrestrial mammals.
The mechanisms underlying the spectral tuning of two of
these blue-shifted pigments have recently been elucidated
and depend on three amino acid substitutions (83Asn,
292Ser, and 299Ser) in dolphin rhodopsin,
but only one amino acid substitution (308Ser)
in the dolphin long-wavelength-sensitive pigment. The objective
of this study was to investigate the molecular basis for
changes in the spectral sensitivity of rod visual pigments
from seven distantly related marine mammals. The results
show a relationship between blue-shifted rhodopsins (λmax
≤ 490 nm), deep-diving foraging behavior, and the substitutions
83Asn and 292Ser. Species that forage
primarily near the surface in coastal habitats have a rhodopsin
with a λmax similar to that of terrestrial
mammals (500 nm) and possess the substitutions 83Asp
and 292Ala, identical to rhodopsins from terrestrial
mammals. |
