Also transports homocysteine (Jiang et al., 2007). AscT1 is the Syncytin-1 (Q9UQF0) receptor. Syncytin-1, of 538 aas with 4-7 TMSs, is a viral fusion protein and is involved in the development of multiple sclerosis (Antony et al. 2007). Mutation causes nuerological problems including global developmental delay, severe progressive microcephaly, seizures, spasticity and thin corpus callosum (CC) Homo sapiens (Human) 2 Cluster1 CharProtDB::CH_091706 neutral amino acid transporter B(0) Mus musculus 2 Cluster1 SwissProt::P51912 AAAT_MOUSE Neutral amino acid transporter B(0); ATB(0); ASC-like Na(+)-dependent neutral amino acid transporter ASCT2; Insulin-activated amino acid transporter; Sodium-dependent neutral amino acid transporter type 2; Solute carrier family 1 member 5 Mus musculus (Mouse) 2 Cluster1 TCDB::P51912 2.A.23.3.2 Insulin-activated, Na+-dependet amino acid (serine, alanine, glutamate, glutamine and other neutral amino acids):amino acid antiporter (Ndaru et al. 2019).
