Abstract
It has long been surmised that cellular microtubules are capped at the minus ends to prevent their depolymerization. A recent study provides the first definitive identification of a minus-end-specific capping protein, termed Patronin, which protects the microtubule arrays of both mitotic and interphase cells.
