Overexpression of X-box binding protein-1 led to a marked increase in luciferase activity in P19 cells transfected with the Slc38a1 reporter plasmid. These results suggest that theanine accelerates cellular proliferation and subsequent neuronal specification through a mechanism relevant to upregulation of Slc38a1 gene in undifferentiated neural progenitor cells

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.
