General Information and Variability Data of DT
Gene Name SLC43A2
Protein Name L-type amino acid transporter 4
Synonyms LAT4; Large neutral amino acids transporter small subunit 4; SLC43A2; Solute carrier family 43 member 2
Gene ID
UniProt ID
DT Family Major Facilitator Superfamily (MFS)
L-Amino Acid Transporter-3 (LAT3) Family
Tissue Specificity Detected in several tissues with higherexpression in placenta, kidney and peripheral blood leukocytes. Inthe kidney, is detected in epithelial cells of the distal tubuleand collecting duct. In the intestine, is expressed mainly incrypt cells of the intestinal microvilli and epithelial cells inthe base of the villus.
Function This sodium-, chloride-, and pH-independent transporter is for large neutral amino acids.
