Sodium-dependent lysophosphatidylcholine (LPC) symporter, which plays an essential role for blood-brain barrier formation and function. Specifically expressed in endothelium of the blood-brain barrier of micro-vessels and transports LPC into the brain. Transport of LPC is essential because it constitutes the major mechanism by which docosahexaenoic acid (DHA), an omega-3 fatty acid that is essential for normal brain growth and cognitive function, enters the brain. Transports LPC carrying long-chain fatty acids such LPC oleate and LPC palmitate with a minimum acyl chain length of 14 carbons. Does not transport docosahexaenoic acid in unesterified fatty acid. a 1-acyl-sn-glycero-3-phosphocholine(in) + Na(+)(in) = a 1-acyl-sn-glycero-3-phosphocholine(out) + Na(+)(out) 1-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phosphocholine(in) + Na(+)(in) = 1-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phosphocholine(out) + Na(+)(out) 1-(9Z-octadecenoyl)-sn-glycero-3-phosphocholine(in) + Na(+)(in) = 1-(9Z-octadecenoyl)-sn-glycero-3-phosphocholine(out) + Na(+)(out) 1-hexadecanoyl-sn-glycero-3-phosphocholine(in) + Na(+)(in) = 1-hexadecanoyl-sn-glycero-3-phosphocholine(out) + Na(+)(out) a 1-acyl-sn-glycero-3-phosphoethanolamine(in) + Na(+)(in) = a 1-acyl-sn-glycero-3-phosphoethanolamine(out) + Na(+)(out) Expressed in the developing nervous system. Morpholino knockdown of the gene results in early postnatal lethality. Belongs to the major facilitator superfamily.
