Summary: 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. Used to study spastic tetraplegia, thin corpus callosum, and progressive microcephaly. 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).

results strongly suggest that combinations of amino acid sequence changes and N-linked oligosaccharides in a critical carboxyl-terminal region of extracellular loop 2 (ECL2) control retroviral utilization of both the ASCT1 and ASCT2 receptors

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
