title: Calcium Builds Strong Host-Parasite Interactions.
abstract: Apicomplexan parasite invasion of host cells is a multistep process, requiring coordinated events. In this issue of Cell Host & Microbe, Paul et al. (2015) and Philip and Waters (2015) leverage experimental genetics to show that the calcium-regulated protein phosphatase, calcinuerin, regulates invasion in multiple parasite species.
