Abstract excerpt
AX15 is a mutein of naturally occurring human ciliary neurophic factor (hCNTF), with improved biological activity, stability and solubility. AX15 is susceptible to protease degradation when expressed in Pichia pastoris. Amino acid sequencing revealed the degradation was occurred behind position 12 and 13 amino acid residues, which constitute a dibasic site, RR. Based on the substrate specificity of KEX2, a KEX2...
