Is predicted to encode a protein with the following domains: Rab-GTPase-TBC domain; PTB/PI domain; Kinesin protein; Kinesin-like; Rab-GTPase-TBC domain superfamily; Rab GTPase-activating protein 1; and PH-like domain superfamily. Is an ortholog of C. elegans tbc-11. In C. elegans, tbc-11 is involved in RNA localization and cuticle development.
