Abstract
- The sorting nexin (SNX) protein family is implicated in regulating membrane traffic, but the mechanism is still unknown. We show that SNX3 is associated with the early endosome through a novel motif (PX domain) capable of interaction with phosphatidylinositol-3-phosphate (Ptdlns(3)P). Overexpression of SNX3 alters endosomal morphology and delays transport to the lysosome. Transport from the early to the recycling endosome is affected upon microinjection of SNX3 antibodies. Our results highlight a novel mechanism by which SNX proteins regulate traffic and uncover a novel class of effectors for Ptdlns(3)P. [ABSTRACT FROM AUTHOR]
