BimC

From Wikipedia, the free encyclopedia

bimC is a subfamily of KRPs and it's function is to separate the duplicated centrosomes during mitosis.

Early in prophase, while the nuclear envelope is still intact, dynamic microtubules from each aster spindel overlap at their plus ends. KRPs of the bimC family self associate through their tails forming a bipolar motor (like myosin II). These bipolar motors slide the oppositely oriented microtubule past each other, therby pushing the spindle poles apart (sliding of antiparallel microtubels).
