A plastid two-pore channel essential for inter-organelle communication and growth of Toxoplasma gondii

Abstract

Two-pore channels (TPCs) are cation channels that localize to acidic organelles to regulate Ca2+ dependent events. Here, Li et al. characterize a TPC from Toxoplasma gondii(TgTPC) that localizes to the apicoplast, is critical for maintaining its integrity and relevant for Ca2+ uptake from the ER through stabilizing inter-organelle contact.
