Also known as: LAT2; LPI-PC1
Summary: Enables several functions, including neutral L-amino acid transmembrane transporter activity; protein heterodimerization activity; and secondary active transmembrane transporter activity. Involved in L-alanine import across plasma membrane; L-leucine import across plasma membrane; and thyroid hormone transport. Located in basolateral plasma membrane and microvillus membrane.

Annotation information: Note: LAT2 (Gene ID: 7462) and SLC7A8 (Gene ID: 23428) share the LAT2 symbol/alias in common. LAT2 is sometimes used as an alternative name for solute carrier family 7 member 8 (SLC7A8), which can be confused with the official symbol for linker for activation of T cells family member 2 (LAT2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

RNA

NR_049767.2 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (5) uses an alternate 5'-most exon and lacks two consecutive internal exons, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 3, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
