Key result
The N-terminal domain of thrombopoietin, containing two disulfide bonds (Cys7-Cys151 and Cys29-Cys85), is essential for its biological activity, whereas the C-terminal domain is not directly required.

May guide TPO mimetic engineering for thrombocytopenia; leaves open in vivo validation of domain effects.
Takashi Kato (1996) studied this question. Thrombopoietin (TPO) purification and structural characterization was evaluated on TPO biological activity and structural characteristics. The N-terminal domain of thrombopoietin, containing two disulfide bonds (Cys7-Cys151 and Cys29-Cys85), is essential for its biological activity, whereas the C-terminal domain is not directly required.
