**Background of LAT2 Antibody**
The L-type amino acid transporter 2 (LAT2), encoded by the *SLC7A8* gene, is a sodium-independent neutral amino acid transporter belonging to the solute carrier (SLC) family. It facilitates the cellular uptake of essential branched-chain and aromatic amino acids (e.g., leucine, phenylalanine) by forming a heterodimeric complex with the heavy chain subunit 4F2hc (CD98hc). Primarily expressed in polarized epithelial cells (e.g., kidney, intestine) and the blood-brain barrier, LAT2 supports nutrient absorption, neurotransmitter synthesis, and cellular metabolism.
LAT2 has gained attention in cancer research due to its overexpression in certain tumors, where it fuels cancer cell proliferation by sustaining amino acid demand. Dysregulation of LAT2 is also implicated in neurological disorders (e.g., Alzheimer’s disease) and metabolic conditions. Antibodies targeting LAT2 are critical tools for detecting its expression, localization, and function in tissues or cell lines. They are widely used in techniques like Western blotting, immunohistochemistry, and flow cytometry to study LAT2’s role in health and disease. Commercial LAT2 antibodies vary in specificity, often validated against epitopes in cytoplasmic or extracellular domains. Researchers must verify antibody performance in their experimental models, as cross-reactivity with related transporters (e.g., LAT1/SLC7A5) may occur. Recent studies continue to explore LAT2 as a potential therapeutic target or biomarker in precision medicine.
