TPO is a lineage-specific growth factor produced in the liver, kidney and skeletal muscle. It stimulates the proliferation and maturation of megakaryocytes, and promotes increased circulating levels of platelets in vivo. TPO signals thro μgh the c-mpl receptor, and acts as an important regulator of circulating platelets. Human and murine TPO exhibit cross-species reactivity. The human TPO gene encodes for a 353 amino acid glycoprotein, which contains a 21 amino acid signal sequence, a 15 amino acid erythropoietin-like domain, and a highly glycosylated 179 amino acid C-terminal domain. Recombinant Human TPO is a fully biologically active 174 amino acid polypeptide (18.6 kDa), which contains the erythropoietin-like domain of the full length TPO protein.

Protein Information
| UniProt ID | P40225 |
|---|---|
| Molecular Weight | 18.6 kDa |
| Sequence Similarities | Belongs to the EPO/TPO family. |
| Protein Length | Protein fragment |
| Cellular Localization | Secreted. |
| Domain | Two-domain structure with an erythropoietin-like N-terminal and a Ser/Pro/Thr-rich C-terminal. |
| Function | Lineage-specific cytokine affecting the proliferation and maturation of megakaryocytes from their committed progenitor cells. It acts at a late stage of megakaryocyte development. It may be the major physiological regulator of circulating platelets. |
| Involvement in Disease | Defects in THPO are a cause of essential thrombocythemia (ET). ET is inherited as an autosomal dominant trait which is characterized by elevated platelet levels due to sustained proliferation of megakaryocytes, and frequently lead to thrombotic and haemorrhagic complications. |
