Platelet production in blood is regulated by a lineage specific humoral factor, thrombopoietin (TPO). The amino terminal domain of TPO (TPO-N) is responsible for the signal transduction mediated by the TPO receptor, c-mpl. From the predicted length of helices we found that TPO-N belongs to the long-chain subfamily of the four-helix bundle cytokine family.(More)
The extracellular domain (edMpl) of human thrombopoietin (TPO) receptor, c-Mpl was expressed in Escherichia coli by changing some nucleotides before and after the translation initiation codon. The mutations increased the expression by approx. 15-fold. The inclusion bodies were solubilized in 8 M guanidine-HCl under reducing conditions and refolded using a(More)
