...Manuel Palacín ABSTRACT The currently identified cDNA clones of mammalian amino acid transporters can be grouped into five different families. One family is composed of the proteins rBAT and the heavy chain (hc) of the cell surface antigen 4F2. RNAs encoding these two proteins induce a system b o...

The other class consists of two known genes, rBAT ( r elated to B system α mino acid t...
