alternative products:A number of isoforms are produced by alternative initiation. Isoforms start at multiple alternative CUG and GUG codons,function:Has a broad substrate specificity, a preference for zwitterionic amino acids, and a sodium-dependence. It accepts as substrates all neutral amino acids, including glutamine, asparagine, and branched-chain and aromatic amino acids, and excludes methylated amino acids, anionic amino acids, and cationic amino acids. Act as a cell surface receptor for feline endogenous virus RD114, baboon M7 endogenous virus and type D simian retroviruses.,similarity:Belongs to the sodium:dicarboxylate (SDF) symporter (TC 2.A.23) family.,subcellular location:Identified by mass spectrometry in melanosome fractions from stage I to stage IV.,tissue specificity:Placenta, lung, skeletal muscle, kidney, pancreas, and intestine.,
Cell membrane ; Multi-pass membrane protein . Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
