background:
Component of the SKA1 complex, a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation. The SKA1 complex is a direct component of the kinetochore-microtubule interface and directly associates with microtubules as oligomeric assemblies. The complex facilitates the processive movement of microspheres along a microtubule in a depolymerization-coupled manner. In the complex, it mediates the microtubule-stimulated oligomerization.
Function:
Component of the SKA1 complex, a microtubule-bindingsubcomplex of the outer kinetochore that is essential for properchromosome segregation. The SKA1 complex is a direct component ofthe kinetochore-microtubule interface and directly associates withmicrotubules as oligomeric assemblies. The complex facilitates theprocessive movement of microspheres along a microtubule in adepolymerization-coupled manner. In the complex, it mediates themicrotubule-stimulated oligomerization.
Subunit:
Component of the SKA1 complex, composed of SKA1, SKA2 andSKA3. The core SKA1 complex is composed of 2 SKA1-SKA2heterodimers, each heterodimer interacting with a molecule of theSKA3 homodimer. The core SKA1 complex associates with microtubulesand forms oligomeric assemblies. Interacts directly with SKA1.
Subcellular Location:
Cytoplasm, cytoskeleton, spindle.Chromosome, centromere, kinetochore. Note=Localizes to the outerkinetochore and spindle microtubules during mitosis in a NDC80complex-dependent manner.
Similarity:
Belongs to the SKA3 family.
