CC   -!- FUNCTION: Causes the migration of the distal retinal pigment into the
CC       proximal end of the pigment chromatophore cells and thus decreases the
CC       amount of light entering the retinulas. May also function as a
CC       neurotransmitter and/or neuromodulator (By similarity).
CC       {ECO:0000250|UniProtKB:P37085}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:14981133,
CC       ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Eyestalk sinus gland.
CC       {ECO:0000269|PubMed:14981133}.
CC   -!- MASS SPECTROMETRY: Mass=1871.87; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:14981133};
CC   -!- SIMILARITY: Belongs to the arthropod PDH family. {ECO:0000305}.
