TissueNA
Tissue SpecificityHighly expressed in the liver and, at lower levels, in skeletal muscle, including in vastus lateralis, gastrocnemius and soleus (at protein level). Highest mRNA levels are observed in skeletal muscle, and only moderate levels in liver and heart. Weak expression in placenta and lung. {ECO:0000269|PubMed:11872655, ECO:0000269|PubMed:17555403}.
