Tissueplacenta, lung
Tissue SpecificityHighly expressed in kidney, lung, placenta, stomach, skeletal muscle, colon and small intestine. Isoform A is prevalently expressed in the lung, testis, placenta, stomach and colon. Isoform B is more abundant in the brain, kidney and the liver. Isoform C is not detected in brain, heart, liver, kidney and skeletal muscle. Expressed on T-cells in fibrotic liver;
at protein level. Overexpressed in fibrotic and cirrhotic liver. {ECO:0000269|PubMed:11478810, ECO:0000269|PubMed:19508382}.
