Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables L-aspartate transmembrane transporter activity; L-serine transmembrane transporter activity; and neutral L-amino acid transmembrane transporter activity. Involved in L-aspartate import across plasma membrane. Acts upstream of or within serine import across plasma membrane. Located in intermediate filament. Is expressed in several structures, including central nervous system; dorsal root ganglion; lung; nose; and thymus primordium. Human ortholog(s) of this gene implicated in spastic tetraplegia, thin corpus callosum, and progressive microcephaly. Orthologous to human SLC1A4 (solute carrier family 1 member 4).
