3.A.1.204.19
ABC transporter G family member 3, ABCG3; ABCG.3. Also called the white-brown complex homologue protein 3, WBC3, of 730 aas. Homologue of animal eye pigment precursor uptake porters.  The white, scarlet (TC# 3.A.1.204.17), and brown (3.A.1.204.18) genes of Drosophila melanogaster encode ABC transporter proteins involved with the uptake and storage of metabolic precursors to the red and brown eye colour pigments (Mackenzie et al. 2000). May also transport sesquiterpenes, defensive agents or pheromones. (Lefèvre and Boutry 2018).
