Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9-mediated kif15 mutations accelerate axonal outgrowth during neuronal development and regeneration in zebrafish.

ABSTRACT: KIF15, the vertebrate kinesin-12, is best known as a mitotic motor protein, but continues to be expressed in neurons. Like KIF11 (the vertebrate kinesin-5), KIF15 interacts with microtubules in the axon to limit their sliding relative to one another. Unlike KIF11, KIF15 also regulates interactions between microtubules and actin filaments at sites of axonal branch formation and in growth cones. Our original work on these motors was done on cultured rat neurons, but we are now using zebrafish to extend these studies to an in vivo model. We previously studied kif15 in zebrafish by injecting splice-blocking morpholinos injected into embryos. Consistent with the cell culture work, these studies demonstrated that axons grow faster and longer when KIF15 levels are reduced. In the present study, w
