RT pigments of the European eel.";
RL Proc. R. Soc. B 262:289-295(1995).
CC -!- FUNCTION: Visual pigments such as rhodopsin and porphyropsin are light-
CC absorbing molecules that mediate vision. Rhodopsin consists of an
CC apoprotein, opsin, covalently linked to 11-cis-retinal. This receptor
CC is coupled to the activation of phospholipase C. Porphyropsin consists
CC of opsin covalently linked to 11-cis 3,4-didehydroretinal.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Absorption:
CC Abs(max)=~482 nm;
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
CC -!- TISSUE SPECIFICITY: Rod shaped photoreceptor cells which mediates
CC vision in dim light.
CC -!- DEVELOPMENTAL STAGE: When eel matures sexually and migrates back to
CC deep sea breeding grounds the visual pigments in its rod photoreceptors
CC change from being maximally sensitive to green light to being maximally
CC sensitive to blue light. In part, this change in sensitivity is due to
CC a change in the opsin component of the visual pigment molecule; this
CC blue sensitive rhodopsin is expressed during life in bluer oceanic
CC waters.
CC -!- PTM: Phosphorylated on some or all of the serine and threonine residues
CC present in the C-terminal region.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family. Opsin
CC subfamily. {ECO:0000255|PROSITE-ProRule:PRU00521}.
