Abstract: | Summary The nine N-terminal amino acids of signal peptide differ between human and mouse granulocyte-colony stimulating factors (G-CSF). To study the function of this non-conserved sequence, cDNA lacking the sequence has been constructedinvitro. The deleted signal peptide promoted the secretion of hG-CSF in CHO cells. |
