    basic FUNCTION
  • displays an oscillatory expression profile in Brown adipose tissue and liver, consistent with a circadian rhythm
  • plays potentially a role in adaptive thermogenesis
  • is potentially a novel lung cancer tumor suppressor gene that regulates cell cycle progression and matrix attachment
  • critical mediator of TM (Tunicamycin) toxicity, and having a critical role by acting as a putative TM transporter at the plasma membrane
  • is a nutritionally regulated gene that plays myriad roles in body growth and development, motor function, and lipid metabolism
  • is a key regulator of BBB function that may act by suppressing transcytosis in CNS endothelial cells
  • is required for brain uptake of docosahexaenoic acid (DHA), an omega-3 fatty acid that is essential for normal brain growth and cognitive function
  • is specifically expressed on the cell membrane of brain-microvascular endothelial cell (BMEC) and is implicated in the delivery of some substances across the blood-brain barrier (BBB)
  • sodium-dependent lysophosphatidylcholine transporter expressed at the blood-brain barrier endothelium
  • uniquely transports lipids, implying that MFSD2A harbors unique structural features and transport mechanism
  • is essential for sphingosine-1-phosphate (S1P) export from endothelial cells in the brain
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • MFSD2A and SPNS2 form a protein complex to ensure the efficient transport of S1P
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • receptor for syncytin-2 (ERVFRD-1) in the placenta that mediates cell fusion
  • MFSD2A is the Syncytin-2 (ERVFRD1) receptor, and is important for trophoblast fusion
  • is a fasting-induced gene regulated by both PPARA and glucagon signaling in the liver
  • lysophosphatidylcholine (LPC) transport via MFSD2A is an important pathway for fatty acid docosahexaenoic acid (DHA) uptake in eye and for development of photoreceptor membrane discs

  • Mfsd2a KO mice exhibited a specific reduction in outer rod segment length, disorganized outer rod segment discs, and mislocalization of and reduction in rhodopsin early in postnatal development without loss of photoreceptors
  • gene-targeted Mfsd2a knockout mice are smaller, leaner, and have decreased serum, liver and brown adipose triglycerides
