Tissuetestis, thyroid
Tissue SpecificityHighest expression observed in liver, spleen and testis;
moderate expression in the choroid plexus, hippocampus, cerebrum and cerebellum of brain, and in kidney cortex and kidney medulla. Also observed in heart, pancreas, muscle, lung, placenta, stomach and small intestine. Weakest expression seen in peripheral blood lymphocytes, colon, duodenum, jejunum, ileum and skeletal muscle. {ECO:0000269|PubMed:10978526, ECO:0000269|PubMed:11087115, ECO:0000269|PubMed:17715183, ECO:0000269|PubMed:26447209}.;
