LIPID TRANSPORT

Fatty acid transporter MFSD2A is a multifunctional gatekeeper in brain and placenta

MFSD2A mediates uptake of the essential fatty acid DHA across the blood–brain barrier. Separately, via interactions with syncytin-2, MFSD2A contributes to the formation of the mother–fetus placental boundary. Cryo-EM analysis of a human MFSD2A–syncytin-2 complex provides new insights into how MFSD2A performs these dual roles.
