Protein attributes
| Sequence length | 541 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| 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. Acts as a cell surface receptor for feline endogenous virus RD114, baboon M7 endogenous virus and type D simian retroviruses. Ref.2 Ref.3 |
| Subcellular location | Membrane; Multi-pass membrane protein Probable. Melanosome. Note: Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Ref.11 |
| Tissue specificity | Placenta, lung, skeletal muscle, kidney, pancreas, and intestine. |
| Sequence similarities | Belongs to the sodium:dicarboxylate (SDF) symporter (TC 2.A.23) family. SLC1A5 subfamily. [View classification] |

Alternative products
| This entry describes 2 isoforms produced by alternative splicing and alternative initiation. [Align] [Select] Note: A number of isoforms are produced by alternative initiation. Isoforms start at multiple alternative CUG and GUG codons. | ||||||
| Isoform 1 (identifier: Q15758-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q15758-2) The sequence of this isoform differs from the canonical sequence as follows: 1-203: MVADPPRDSK...SNLVSAAFRS → M | ||||||
| Note: No experimental confirmation available. |
