Romiplostim (Gly-001CL)

Romiplostim is a thrombopoiesis stimulating dimer Fc-peptide fusion protein (peptibody) to increase platelet production through activation of the thrombopoietin receptor. The peptibody molecule has two identical single-chain subunits, each one is made up of 269 amino acid residues. Each subunit consists of an IgG1 Fc carrier domain that is covalently attached to a polypeptide sequence that contains two binding domains to interact with thrombopoietin receptor c-Mpl. Each domain consists of 14 amino acids. Interestingly, romiplostim's amino acid sequence is not similar to that of endogenous thrombopoietin. Romiplostim is produced by recombinant DNA technology in Escherichia coli.

Mechanism of Action
Romiplostim is a thrombopoietin receptor agonist that activates intracellular transcriptional pathways via c-Mpl to increase production of platelets. It also works similarly to thrombopoietin (TPO), an endogenous glycoprotein hormone that regulates the production of platelets in the bone marrow.
