The Vps13-like protein BLTP2 regulates phosphatidylethanolamine levels to maintain plasma membrane fluidity and breast cancer aggressiveness

Banerjee et al. report that the Vps13-like lipid transport protein BLTP2 regulates plasma membrane fluidity by maintaining phosphatidylethanolamine homeostasis. BLTP2 also facilitates breast cancer cell growth, suggesting a separate role in tumorigenesis.
