Sialin

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Sialin (495 aa, ~55 kDa) is encoded by the human SLC17A5 gene. This protein is involved in proton-dependent transport of nitrate ions and sialic acid and the regulation of amino acid and peptide uptake by synaptic vesicles.

**Synonyms:** - AST - H(+)/Nitrate Cotransporter - H(+)/Sialic Acid Cotransporter - Membrane Glycoprotein HP59 - SLC17A5 - Solute Carrier Family 17 Member 5 - VEAT - Vesicular Excitatory Amino Acid Transporter
