Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motility and fusion. They share a fold in common with all Ras GTPases: this is a six-stranded beta-sheet surrounded by five alpha-helices [1].

Rubicon (RUBCN) negatively regulates autophagy and endolysosomal trafficking by inhibiting PI3K complex II (PI3KC3-C2), which impairs autophagosome maturation process. PLEKHM1 is an adapter protein that regulates Rab7-dependent and HOPS complex-dependent fusion events in the endolysosomal system and couples autophagic and the endocytic trafficking pathways [3,4]. On the other hand, Pacer positively regulates autophagy, promoting autophagosome maturation by facilitating the biogenesis of phosphatidylinositol 3-phosphate (PtdIns3P) in late steps of autophagy; it antagonises RUBCN [5]. This domain contains nine conserved cysteines and one conserved histidine, which have been predicted to bind divalent zinc cations being required for Rubicon and PLEKHM1 to interact with Rab7.
