LMTK3 inhibition affects microtubule stability.

In addition, to confirm the involvement of NUSAP1 in the C28-mediated effect on microtubule stability and cell cycle arrest, we investigated the levels of cyclin-dependent kinase 1 (CDK1), a previously described NUSAP1-regulated protein [[12]], and phospho- III tubulin (S172). Taken together, although C28 can potentially bind tubulin, its relatively low binding affinity to purified tubulin dimer and the lack of any observable effect on tubulin polymerization suggest that C28 does not confer its effects by direct inhibition of tubulin polymerization. Considering the role of kinase inhibitors on microtubules [[4]], we investigated the possibility that C28 is a direct tubulin-targeting agent by employing an in vitro tubulin polymerization assay.
