Claim: MAP4 (encoded by the MAP4 gene) interacts with Cyclin B and affects microtubule properties and cell cycle progression.
Evidence: Microtubule-associated protein 4 is a protein that in humans is encoded by the MAP4 gene. Cyclin B was found to interact with this protein, which targets cell division cycle 2 (CDC2) kinase to microtubules. The phosphorylation of this protein affects microtubule properties and cell cycle progression.
