Tissue non-specific alkaline phosphatase (TNAP) is an isoenzyme of alkaline phosphatase encoded by the ALPL gene in the human body. TNAP is mainly present in tissues such as bone, liver, and kidneys. It plays a crucial role in bone by participating in the metabolism of phosphates and the mineralization process of the skeleton. Additionally, TNAP also plays a role in fetal development and growth. In clinical practice, the activity level of TNAP is also used as a diagnostic marker for bone diseases and liver diseases. Research also indicates that TNAP may play an important role in human diseases, including bone disorders such as osteoporosis and rickets, as well as other conditions such as cancer and inflammatory diseases. Tissue non-specific alkaline phosphatase (TNAP) is found in many different organs, but abundant in the skeletal, hepatic and renal tissues. TNAP is a homodimeric protein and in its structure, in addition to one phosphate anion, each monomer is composed of three metallic ions (one Mg2+ and two Zn2+ cations). Each subunit contains an extended central core β-beach with α-helices, while an extended N-terminal α-helix has a “crown domain”. The crown domain can be characterised as a loose interfacial loop with amino acid residues involved in stabilizing the binding of non-competitive inhibitors to the enzyme.
