Kinesin Family, Member 2B (KIF2B)

Kinesin Family Member 2B belongs to the kinesin-like protein family. Contains 1 kinesin-motor domain.MCAK/KIF2 subfamily.Highest level in lung. High level in ovary, moderate levels in heart, kidney, placenta, skeletal muscle and spleen (at protein level). Pancreas and spleen express a shorter isoform (at protein level).Osteosarcoma cells (U2OS) lacking KIF2B show disorganised often monopolar mitotic spindles, severely reduced velocity of chromosome movement and blocked cytokinesis. Bipolar mitotic spindles can be restored by simultaneous depletion of KIF2B, KIFC1 and NUMA1.Plus end-directed microtubule-dependent motor required for spindle assembly and chromosome movement. Has microtubule depolymerization activity.
