The protein–protein interaction between Rab39a and natural substrate [25]: The Rab39a (yellow) interacts with DENND5B (green). The specific binding residues of Rab39a are shown in red-labeled sticks (CYS41, VAL45, PHE49, SER51, ARG61 and LYS63) in Rab39a. The residues of DENND5B are represented in violet color, while the H-bond interactions in blue color and π interactions in orange lines.
