Tubulin polymerization-IN-43 is an inhibitor of tubulin polymerisation.Tubulin polymerization-IN-43 has multiple effects, disrupting the cellular microtubule network by targeting the colchicine locus and promoting cell cycle arrest and apoptosis in leukaemia cells. Tubulin polymerisation-IN-43 has multiple effects, promoting leukaemia cell cycle arrest in G2/M phase and apoptosis by targeting Colchicine sites to disrupt the cellular microtubule network.
