text
| binds to microtubules, localizes on the spindle |
|
localizes to centrosomes and spindle microtubules in early mitosis |
|
distributed diffusely throughout the cytoplasm in interphase but localized to the separating centrosomes in prophase, to the spindle poles and spindle MTs in prometaphase to metaphase, to spindle MTs in anaphase, and to the distal sections of the midbody in cytokinesis |
basic FUNCTION
| binds to microtubules, localizes on the spindle, acts as a scaffold that binds to both STK38 and MOB2, and synergistically activates STK38 with MOB2 |
|
STK3-, FRY-, and MOB2-mediated activation of STK38 is crucial for the fidelity of mitotic chromosome alignment in mammalian cells |
|
evolutionarily conserved protein implicated in cell division and morphology |
|
plays a crucial role in the structural integrity of mitotic centrosomes and in the maintenance of spindle bipolarity by promoting PLK1 activity at the spindle poles in early mitosis |
|
plays a crucial role in PLK1 activation in early mitosis |
|
plays a crucial role in spindle pole integrity by promoting PLK1 activity on centrosomes in early mitosis |
|
evolutionarily conserved protein that binds to MTs (microtubules) and colocalizes with acetylated MTs in the mitotic spindle |
|
plays a crucial role in promoting the level of MT acetylation in the mitotic spindle by inhibiting the tubulin-deacetylase activity of SIRT2 |
