9.A.78.1.2
Protein retinal degeneration B, RdgB, of 1259 aas, possibly with a central 8 TMSs unit in a 4 + 4 TMS arrangement. It catalyzes the transfer of phosphatidylinositol (PI) and phosphatidic acid (PA) between membranes (Garner et al. 2012). It may control the phosphatidylinositol concentration in transport vesicles
from the subrhabdomeric cisternae (SRC) to the rhabdomere as well as functioning as a calcium transporter (Vihtelic et al. 1991).
