General annotation (Comments)
| Function | Required for normal progression through mitosis. Required for normal congress of chromosomes at the metaphase plate, and for normal rate of chromosomal segregation during anaphase. Plays a role in the regulation of mitotic spindle dynamics. Increases the rate of turnover of microtubules on metaphase spindles, and contributes to the generation of normal tension across sister kinetochores. Recruits KIF2A to the mitotic spindle and spindle poles. May participate in p53/TP53-regulated growth suppression. Ref.8 Ref.11 |
| Subunit structure | Interacts with APC2 By similarity. Interacts with KIF2A. Ref.8 |
| Subcellular location | Cytoplasm. Cytoplasm › cytoskeleton › spindle. Cytoplasm › cytoskeleton › spindle pole. Note: Detected at the mitotic spindle and spindle poles. Diffusely distributed throughout the cell during interphase. Ref.1 Ref.8 Ref.11 |
| Tissue specificity | Widely expressed in adult and fetal tissues, with highest expression in the adult brain and fetal thymus. Not detected in adult skeletal muscle. Ref.1 |
| Post-translational modification | Phosphorylated during mitosis. Ref.8 |
| Sequence similarities | Belongs to the PSRC1 family. |
