The SLC45A2 gene (also called MATP ) provides instructions for making a protein that is located in specialized cells called melanocytes. These cells produce a pigment called melanin, which is the substance that gives skin, hair, and eyes their color. READ MORE

The SLC46A1 gene provides instructions for making a protein called the proton-coupled folate transporter (PCFT). This protein is found within the membrane of cells, where it helps transport certain B vitamins called folates into the cell. PCFT is pri READ MORE

The SLC4A1 gene provides instructions for making a protein known as anion exchanger 1 (AE1). This protein transports negatively charged atoms (anions) across cell membranes. Specifically, AE1 exchanges negatively charged atoms of chlorine (chloride i READ MORE

The SLC52A2 gene provides instructions for making a riboflavin transporter protein called RFVT2 (formerly known as RFT3). This protein moves (transports) a vitamin called riboflavin (also called vitamin B 2 ) across the cell membrane. The RFVT2 prote READ MORE

The SLC52A3 gene (previously called the C20orf54 gene) provides instructions for making a riboflavin transporter protein called RFVT3 (formerly known as RFT2). This protein moves (transports) a vitamin called riboflavin (also called vitamin B 2 ) acr READ MORE

The SLC5A1 gene provides instructions for producing a protein called sodium/glucose cotransporter protein 1 (SGLT1). This protein is found mainly in the intestinal tract and the kidneys. It spans the membrane of cells and moves (transports) two sugar READ MORE

The SLC5A5 gene provides instructions for making a protein called sodium (Na)-iodide symporter or NIS. This protein transports iodide, a negatively charged version of iodine, into cells of certain tissues. The NIS protein is found primarily in the th READ MORE

The SLC6A19 gene provides instructions for making a protein called system B(0) neutral amino acid transporter 1 (B 0 AT1). This protein transports certain protein building blocks (amino acids), namely those with a neutral charge, into cells. B 0 AT1 READ MORE

The SLC6A3 gene provides instructions for making a protein called the dopamine transporter or DAT. This protein is embedded in the membrane of certain nerve cells (neurons) in the brain, where it transports a molecule called dopamine into the cell. D READ MORE

The SLC6A8 gene provides instructions for making a protein called sodium- and chloride-dependent creatine transporter 1. This protein transports the compound creatine into cells. Creatine is needed for the body to store and use energy properly. READ MORE

The SLC7A7 gene provides instructions for producing a protein called y+L amino acid transporter 1 (y+LAT-1), which is involved in transporting certain protein building blocks (amino acids), namely lysine, arginine, and ornithine. The transportation o READ MORE

The SLC7A9 gene provides instructions for producing one part (subunit) of a protein made primarily in the kidneys. This subunit joins with another protein subunit, produced from the SLC3A1 gene, to form a transporter protein complex. During the proce READ MORE
