MBAPs bridge brassinosteroid signaling and cortical microtubules
Cell surface receptors govern a large part of responses to exogenous or endogenous stimuli. In plants, several layers of mechanisms are known to adjust the level of receptor signaling, but the entire mechanisms are yet to be identified. Our team employs BRI1, a major brassinosteroid hormone receptor, as a representative model to understand how receptor signaling is controlled at molecular levels. Recently, we have identified novel BRI1 interactors that localize to cortical microtubules, named MBAPs. In this presentation, the pivotal roles of these molecules in both BR signaling and microtubule regulation will be discussed.
