Also known as: Glyt1; Glyt-1
Summary: Enables glycine:sodium symporter activity. Involved in several processes, including glycine import across plasma membrane; positive regulation of biosynthetic process; and regulation of glycinergic synaptic transmission. Acts upstream of or within glycine secretion, neurotransmission. Located in plasma membrane. Is expressed in several structures, including central nervous system; eye; genitourinary system; gut; and liver and biliary system. Used to study glycine encephalopathy. Orthologous to human SLC6A9 (solute carrier family 6 member 9). [provided by Alliance of Genome Resources, Nov 2024]

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.
