Adaptor that targets bridge-like transporters (BLTPs) to ER-PM contact sites; binds to lipid transporters such as Fmp27p and Hob2p and targets them to ER-PM contact sites to enable the rapid transfer of bulk lipids between organelles, as part of ergosterol homeostasis; green fluorescent protein (GFP)-fusion protein localizes to the cell periphery; human homologs EEIG1 and EEIG2 also function as BLTP adaptors at ER-PM contact sites
