Purity: > 95% by SDS - PAGE Format: Liquid. In Phosphate Buffered Saline (pH 7.4) containing 10% glycerol.. SLC3A2, also known as 4F2 cell-surface antigen heavy chain isoform c, is a single-pass type I I membrane protein which belongs to the SLC3A transporter family. It is expressed ubiquitously in all tissues tested with highest levels detected in kidney, placenta and testis and weakest level in thymus. This protein is required for the function of light chain amino-acid transporters and also involved in sodium-independent, high-affinity transport of large neutral amino acids such as phenylalanine, tyrosine, leucine, arginine and tryptophan. This protein involved in guiding and targeting of LAT1 and LAT2 to the plasma membrane. Recombinant human SLC3A2, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
