Profilin binds microtubules in vitro. However, a new study by Vitriol and colleagues (https://doi.org/10.1083/jcb.202309097) now suggests that effects of profilin on microtubule dynamics in cells are indirect and result from its impact on actin dynamics rather than its direct binding to microtubules.
原肌球蛋白在体外结合微管。然而,Vitriol 及其同事的一项新研究(https://doi.org/10.1083/jcb.202309097)现在表明,原肌球蛋白对细胞中微管动力学的影响是间接的,是由于其对肌动蛋白动力学的影响,而不是其直接与微管结合。
