General annotation (Comments)
| Function | 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. Ref.11 Ref.12 |
| Subunit structure | Interacts with AP5Z1, AP5B1, AP5S1 and SPG11. Interacts with TTC19 and KIF13A. Ref.11 Ref.12 |
| Subcellular location | Cytoplasm › cytoskeleton › centrosome. Midbody. Note: Localizes to the centrosome during all stages of the cell cycle. Recruited to the midbody during cytokinesis by KIF13A. Ref.11 |
| Tissue specificity | Strongest expression in the adrenal gland, bone marrow, adult brain, fetal brain, lung, placenta, prostate, skeletal muscle, testis, thymus, and retina. Intermediate levels are detected in other structures, including the spinal cord. Ref.7 |
| Domain | The FYVE-type zinc finger mediates binding to phosphatidylinositol 3-phosphate and recruitment to the midbody during cytokinesis. Ref.11 |
| Involvement in disease | Spastic paraplegia autosomal recessive 15 (SPG15) [MIM:270700]: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SPG15 is a complex form associated with additional neurological symptoms such as cognitive deterioration or mental retardation, axonal neuropathy, mild cerebellar signs, and, less frequently, a central hearing deficit, decreased visual acuity, or retinal degeneration. |
| Sequence similarities | Contains 1 FYVE-type zinc finger. |
| Sequence caution | The sequence BAG11658.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence CAD97882.1 differs from that shown. Reason: Erroneous termination at position 1463. Translated as Gln. |
