retinene

 [ret´ĭ-nēn]
an ocular pigment derived from vitamin A and formed by the bleaching action of light on rhodopsin. It occurs in two forms: retinene1 is retinal (def. 2), and retinene2 is dehydroretinal.

ret·i·nal·de·hyde

(ret'i-nal'dĕ-hīd),
Retinol oxidized to a terminal aldehyde; retinal; a carotene released (as all-trans-retinal) in the bleaching of rhodopsin by light and the dissociation of opsin in the vision cycle.

To verify whether the two GPCRs were indeed able to form photopigments in a manner similar to opsin proteins, the two proteins were expressed in HEK293T cells and incubated with either 11-cis retinal or all-trans retinal.
Incubation of Air-AAR1-Like[DELTA]58 with 11-cis retinal generated a photopigment that apparently reacted after exposure to blue light (~474 nm) but not amber light (~592 nm; not shown) (Fig.
No light responses were detected in mRNA-injected oocytes before the application of 11-cis retinal. Other studies using the same expression system detected no responses in non-injected oocytes after incubation with 11-cis retinal (5).
Figure 1C shows that repetitive flashes of light can evoke repetitive responses from oocytes without the need for additional incubation with 11-cis retinal. This sustained fight sensitivity supports an earlier finding that Limulus metarhodopsin is a relatively stable and photoreversible photoproduct of Limulus rhodopsin (10).
