The steroidogenic acute regulatory (StAR) protein-related lipid transfer (START) domain proteins constitute a family of evolutionarily conserved and widely expressed proteins that have been implicated in lipid transport, metabolism, and signaling. Human StAR-related lipid transfer protein 7 (STARD7, aka GTT1) is a member of the StarD2/phosphatidylcholine transfer protein (PCTP) subfamily that can bind phospholipids and sphingolipids (Flores-Martin et al. 2013). It was first identified as a gene overexpressed in a choriocarcinoma cell line (Durand et al. 2004). Human STARD7 is thought to transport phosphatidylcholine (PC) from ER membranes to mitochondrial membranes, inferred from rat experiments (Horibata & Sugimoto 2010). Increasing evidence suggests that asthma pathogenesis is linked to mitochondrial dysfunction and STARD7 could play a protective role in mucosal tissues by preventing pathogenic immune responses (Yang et al. 2015).
