Enables GTPase activator activity. Involved in positive regulation of early endosome to late endosome transport and regulation of presynaptic dense core granule exocytosis. Located in cholinergic synapse and late endosome. Expressed in gonadal sheath cell; hypodermis; intestine; and pharyngeal muscle cell. Is an ortholog of human TBC1D2 (TBC1 domain family member 2).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
