Mitotic kinesin-like protein 2 (MKLP-2) is an N-terminal motor from the kinesin-6 family that is essential for normal cleavage furrow ingression and cytokinesis. Its activity mediates the relocation of the chromosome passenger proteins Aurora B kinase and survivin from the centromeres to the central spindle in anaphase cells in order to facilitate cytokinesis, avoiding the generation of binucleated cells.{22151} Paprotrain, PAssenger PROteins TRAnsport INhibitor, is the first known inhibitor of MKLP-2. It is a cell-permeable, reversible inhibitor uncompetitive with ATP (Ki = 3.4 μM) and noncompetitive with microtubules (Ki = 1.6 μM), demonstrating ATPase inhibition of basal and microtubule-stimulated activities with IC50 values of 1.35 and 0.83 μM, respectively.{22150} Paprotrain does not inhibit twelve additional kinesins, including the closely related kinesin-6 motors MKLP-1 and MPP1.{22150} Incubation with 10-50 μM paprotrain results in binucleated cells, perturbing relocation of Aurora B kinase and survivin without affecting microtubule polymerization.{22150}
