SLC7A3 solute carrier family 7 member 3 [Homo sapiens (human)] - Gene

Summary

Official Symbol: SLC7A3provided by HGNC
Official Full Name: solute carrier family 7 member 3provided by HGNC
Primary source: HGNC:HGNC:11061
See related: Ensembl:ENSG00000165349 MIM:300443
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: CAT3; ATRC3; CAT-3
Summary: This gene encodes a member of the solute carrier family 7. The encoded protein is a sodium-independent cationic amino acid transporter. Alternate splicing results in multiple transcripts that encoded the same protein.[provided by RefSeq, May 2010]
Expression: Biased expression in endometrium (RPKM 1.9), prostate (RPKM 1.2) and 8 other tissues See more
Orthologs: mouse all

It is concluded that similar to hCAT-1, hCAT-3 activity is decreased by PKC via reduction of transporter molecules in the plasma membrane.

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.
