SLC3A2（solute carrier family 3 member 2），癌症关联基因，基因ID：6520，该基因是溶质载体家族的一员，编码细胞表面的跨膜蛋白蛋白质作为重二聚体的重链存在，通过二硫键共价键连接到几个可能的轻链中的一个。编码的转运蛋白在调节细胞内钙离子水平和转运L型氨基酸中发挥作用。另外，编码不同亚型的剪接转录变体已经被鉴定。[由RefSeq提供，2010年11月]This gene is a member of the solute carrier family and encodes a cell surface， transmembrane protein. The protein exists as the heavy chain of a heterodimer， covalently bound through di-sulfide bonds to one of several possible light chains. The encoded transporter plays a role in regulation of intracellular calcium levels and transports L-type amino acids. Alternatively spliced transcript variants， encoding different isoforms， have been characterized. [provided by RefSeq， Nov 2010]。
