Miscellaneousi

Miscellaneous

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.
Opsin Rh3 is sensitive to UV light.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
