Nucleotide-free structures of Kif20A illuminate the atypical allostery in this mitotic kinesin-6

KIF20A is a critical kinesin for cell division and a promising anti-cancer drug target. The mechanisms underlying its cellular roles remain elusive. Interestingly, unusual coupling between the...

Our recent work in collaboration with the Allingham's lab describing the mechanism of combined motile and depolymerization activities by a kinesin-8 just came out! nature.com/articles/s41467-0…

Kinesin-8-specific loop-2 controls the dual activities of the motor domain according to tubulin...

Nature Communications - Kinesin-8s are dual-activity motor proteins that can move processively on microtubules and depolymerize microtubule plus-ends. This study shows how kinesin-8s alternate...

Glad to see our paper finally coming out with 18 cryo-EM snapshosts of the molecular motor KIF14. biorxiv.org/content/10.1101/…

Structural basis of mechano-chemical coupling by the mitotic kinesin KIF14

KIF14 is a mitotic kinesin protein important for cytokinesis. Its overexpression is associated with a variety of cancers and mutations in KIF14 result in cerebral and renal development defects. Like...
