Luminal heterodimeric amino acid transporter defective in cystinuria

Mutations of the glycoprotein rBAT cause cystinuria type I, an autosomal recessive failure of dibasic amino acid transport (b(0,+) type) across luminal membranes of intestine and kidney cells. Here we identify the permease-like protein b(0,+)AT as the catalytic subunit that associates by a disulfide...
