May be involved in intracellular trafficking. Probable association with membranes. Interacts with ZFYVE16; interaction is required to target it to endosomes. Ubiquitous. In adult brain, it is highly expressed at the mesencephalic level, in the hippocampal formation and medial lemniscus. In cerebellum, it is highly expressed in Purkinje cells and granular layers. Ubiquitously expressed in the embryo, with a higher expression in the intestines. Belongs to the TOM1 family.
