The Secret of Centriole Length: Keep a LID on It

An outstanding challenge in biology is to elucidate the mechanisms that establish and limit organelle structure and size. In this issue of Developmental Cell, Sharma et al. (2016) report how a conserved centriole protein dynamically caps centriole microtubule plus ends to limit the organelle’s length.
