CD98 is a glycoprotein that is a heterodimer composed of SLC3A2 (heavy subunit) and SLC7A5 ( light subunit) that forms the large neutral amino acid transporter (LAT1/LAT2).
LAT1/LAT2 is a heterodimeric membrane transport protein that preferentially transports branched-chain (valine, leucine, isoleucine) and aromatic (tryptophan, tyrosine) amino acids.
- LAT1 is highly expressed in brain capillaries (which form the blood–brain barrier) relative to other tissues.
- LAT2 is localized to the cytoplasm when expressed alone but when coexpressed with SLC3A2/4F2hc, is localized to the plasma membrane. Colocalized with SLC3A2/4F2hc at the basolateral membrane of kidney cortex proximal tubules and small intestine epithelia of the villi.
