Protein attributes

Sequence length	369 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal.
Subcellular location	Membrane; Multi-pass membrane protein.
Tissue specificity	Each Drosophila eye is composed of 800 facets or ommatidia. Each ommatidium contains 8 photoreceptor cells (R1-R8), the R1 to R6 cells are outer cells, while R7 and R8 are inner cells. Rh6 is expressed in a subset of R8 cells, most likely expressed in the subset of R8 cells paired with Rh4-expressing R7 cells (R7y).
Post-translational modification	Phosphorylated on some or all of the serine and threonine residues present in the C-terminal region By similarity.
Sequence similarities	Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.
