General annotation (Comments)
| Function | Acts as a actin nucleation factor, remains associated with the slow-growing pointed end of the new filament. Involved in intracellular vesicle transport along actin fibers, providing a novel link between actin cytoskeleton dynamics and intracellular transport. Required for asymmetric spindle positioning and asymmetric cell division during meiosis. Required for normal formation of the cleavage furrow and for polar body extrusion during female germ cell meiosis. Ref.7 Ref.9 UniProtKB Q9U1K1 |
| Subunit structure | |
| Subcellular location | Cytoplasm › cytoskeleton. Cytoplasm › perinuclear region. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cytoplasmic vesicle membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Note: Detected at the cleavage furrow during asymmetric oocyte division and polar body extrusion By similarity. Punctate spots in perinuclear region and cytoplasm, co-localised with Rab11. Ref.7 |
| Domain | Binds to actin monomers via the WH2 domain By similarity. UniProtKB Q9U1K1 The Spir-box targets binding to intracellular membrane structures. Ref.7 |
| Sequence similarities | Belongs to the spire family. Contains 1 KIND domain. Contains 2 WH2 domains. |
| Sequence caution | The sequence AAI15006.1 differs from that shown. Reason: Erroneous initiation. The sequence AAI25207.1 differs from that shown. Reason: Erroneous initiation. The sequence AAI25208.1 differs from that shown. Reason: Erroneous initiation. The sequence BAA86449.2 differs from that shown. Reason: Erroneous initiation. |
