Predicted to enable lysophosphatidylcholine flippase activity; lysophospholipid:sodium symporter activity; and oleate transmembrane transporter activity. Predicted to be involved in central nervous system development; lipid transport; and transcytosis. Predicted to act upstream of or within several processes, including photoreceptor cell development; regulation of lipid metabolic process; and retina development in camera-type eye. Predicted to be located in plasma membrane. Predicted to be integral component of plasma membrane. Human ortholog(s) of this gene implicated in primary autosomal recessive microcephaly 15. Orthologous to human MFSD2A (major facilitator superfamily domain containing 2A). [provided by Alliance of Genome Resources, Apr 2022]
