TissueNA
Tissue SpecificityIsoform USP25a is found in most adult and fetal tissues;
expression is moderately high in testis, pancreas, kidney, skeletal muscle, liver, lung, placenta, brain, heart, but very low in peripheral blood, colon, small intestine, ovary, prostate, thymus and spleen. Isoform USP25b is found in all tissues except heart and skeletal muscle. Isoform USP25m is heart and skeletal muscle specific. {ECO:0000269|PubMed:10644437, ECO:0000269|PubMed:11597335}.
