Predicted to enable GTPase activity. Involved in endosome membrane tubulation and positive regulation of protein catabolic process. Located in late endosome. Is expressed in several structures, including Bolwig organ; brain; imaginal disc; mushroom body; and synaptic neuropil domain.
FB Description
RabX1 (RabX1) encodes a small GTPase that is involved in the organization of late endosomal compartments. It promotes endolysosomal degradation by establishing tubules connecting late endosomes and lysosomes.
