Required for proper chromosome congression and alignment during mitosis. Required for targeting KIF22/KID to the spindle microtubules.
Belongs to the FAM83 family.
Cytoplasm. Cytoplasm > cytoskeleton > spindle. Cytoplasm > cytoskeleton > spindle pole. Primarily cytoplasmic during interphase, but beginning in prophase, associates with spindle microtubules, with a clear concentration toward the spindle poles. It persists on spindle microtubules through metaphase and anaphase.
