Miscellaneousi

Miscellaneous

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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
