Thrombopoietin Receptor (TPO)

Thrombopoietin receptor agonists activate c-Mpl, the cytokine receptor that controls platelet production. The receptor is encoded by the myeloproliferative leukemia protein (MPL) gene, cloned in 1992 as the human homolog of the viral oncogene v-mpl. Its sequence placed it in the hematopoietic growth factor receptor superfamily. The ligand thrombopoietin (TPO) was identified in 1994 and stimulated megakaryocyte and platelet formation in vivo. TPO binding activates Janus kinase 2 (JAK2) signaling, and the receptor also supports hematopoietic stem cells. Eltrombopag, avatrombopag and lusutrombopag are small-molecule agonists that bind outside the cytokine binding site. Romiplostim is a peptide fused to an antibody Fc fragment that binds the receptor like TPO itself.
