Adherent cells round up before division but it is unclear how detachment is regulated by the cell cycle. In this issue, Jones et al. (2018. J. Cell Biol. https://doi.org/10.1083/jcb.201802088) find the kinase CDK1 maintains adhesion during interphase by phosphorylating integrin adhesome proteins, including the formin FMNL2, and loss of this function of CDK1 activity in G2 triggers adhesion disassembly.
