Rabbit anti Human LAT1 antibody recognizes human LAT1 (L-type amino acid transporter 1), a heterodimeric Na+-independent amino acid transporter protein and member of the amino acid-polyamine-organocation (APC) superfamily, involved in the high-affinity transport of large neutral amino acids, in association with SLC3A2/4F2hc.

LAT1 is highly expressed in the brain and is involved in the transport of L-DOPA across the blood-brain barrier, in brain neurogenesis, and acts as a mediator of L-leucine transport across the inner blood-retinal barrier. LAT1 is involved in the cell membrane transport of the thyroid hormones triiodothyronine (T3) and thyroxine (T4) in the placenta, and is the foremost transporter of tyrosine in fibroblasts.
