Results suggest that ASCT1/2 may play an important role in regulating extracellular d-serine and NMDA receptor-mediated physiological effects and that ASCT1/2 inhibitors have the potential for therapeutic benefit.

ANKRD50 simultaneously engages multiple parts of the SNX27-retromer-WASH complex machinery in a direct and co-operative interaction network that is needed to efficiently recycle the nutrient transporters
Title: Retromer- and WASH-dependent sorting of nutrient transporters requires a multivalent interaction network with ANKRD50.
SLC1A4 deficiency should not be considered a population-specific disorder, and all patients with unexplained severe neurodevelopmental delay and the features outlined should be investigated regardless of ethnicity, as there are no known metabolic markers of this potentially treatable condition.

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.
