basic FUNCTION	playing a role in trafficking proteins, including inflammatory mediators
	playing a role in segregation of intracellular molecules into distinct organelles
	essential for SNARE-mediated membrane trafficking
	key molecule that functions downstream from RAB5, cooperating with ZFYVE20, to regulate the dynamics of the endocytic system in multicellular organisms
	playing a role in Golgi-to-lysosome trafficking
	VPS45 and ZFYVE20 are implicated in post early endosome transport, and their interaction potentially serves as a nexus to promote bidirectional transport along the endosome-to-recycling compartment and endosome-to-Golgi axes

INTERACTION

DNA

RNA

small molecule

protein	interact with its cognate SNARE proteins through distinct mechanisms at different stages in the SNARE assembly/disassembly cycle
	RBSN is a RAB5 effector that bridges an interaction between Rab5 and the Sec1/Munc18-family protein VPS45
	interacts with the divalent Rab4/Rab5 effector, ZFYVE20 and carries out multiple functions in the endocytic/secretory pathways
