Phosphatidylinositol 3-phosphate-binding protein required for the abcission step in cytokinesis: recruited to the midbody during cytokinesis and acts as a regulator of abcission. May also be required for efficient homologous recombination DNA double-strand break repair (By similarity). Interacts with AP5Z1, AP5B1, AP5S1 and SPG11. Interacts with TTC19 and KIF13A (By similarity). Localizes to the centrosome during all stages of the cell cycle. Recruited to the midbody during cytokinesis by KIF13A (By similarity). The FYVE-type zinc finger mediates binding to phosphatidylinositol 3-phosphate and recruitment to the midbody during cytokinesis. Belongs to the ZFYVE26 family.
