Kinesin Family, Member 5B (KIF5B)

Kinesins are microtubule-based motor proteins involved in the transport of organelles in eukaryotic cells. They The predicted 963-amino acid protein has 63% sequence identity to the Drosophila KHC. Immunoblot analysis using antibodies against squid KHC detected a 120-kD protein in CV-1 monkey kidney epithelial cells. Immunoblot analysis using antibodies against squid KHC detected a 120-kD protein in CV-1 monkey kidney epithelial cells. Immunofluorescence studies showed that KNS1 expressed in CV-1 cells had both a diffuse distribution and a filamentous staining pattern that coaligned with microtubules but not vimentin (VIM) intermediate filaments; the KNS1 N- and C-terminal domains, but not the alpha-helical rod domain, also colocalized with microtubules.
