The most common expression strategy for secreting heterologous proteins from filamentous fungus Aspergillus niger is based on fusion with glucoamylase gene which contains cleavage site for kexin protease (KEX2). However, secretion of recombinant prot

When studying two different histidine tags attached to the N-termini of the trimeric cytokine tumor necrosis factor alpha (TNF), the biological activity — measured as cytotoxicity on the L-929 cell line — of both tagged proteins was drastically r

The first essential step in TNF signal transduction is believed to be clustering of the membrane bound receptors around the trimeric TNF molecule. To check if one receptor binding site would be enough to trigger the signal, we tried to prepare severa

Human granulocyte-colony stimulating factor (hG-CSF), an important biopharmaceutical drug used in oncology, is currently produced mainly in Escherichia coli. Expression of human hG-CSF gene in E. coli is very low, and therefore a semisynthetic, codon

The N-terminus of the trimeric TNF-alpha molecule comprises two basic arginines within the short amino-acid sequence VRSSSR, which is here shown to be essential for binding of TNF-alpha to heparin-Sepharose. Mixed trimers containing full-length and D

Attachment of oligo-histidine tag (His-tag) to the protein N- or C-terminus is a good example of early and successful protein engineering to design a unique and generalized purification scheme for virtually any protein. Thus relatively strong and spe

Wild type gene for green fluorescent protein (GFP) was stably integrated into the Pichia pastoris genome and yielded an expression level of over 40% of total cellular protein. The high cytoplasmic concentration of fluorescent (properly folded and pro

Constitutive and thermoinducible expression plasmids based on strong PR,PL promoters from phage lambda were compared for production of TNF-alpha and its analogs under various conditions. Much higher accumulation of TNF was obtained in a constitutive

Our tumor necrosis factor-alpha (TNF-alpha) analog LK-805 (E107K) exhibited twofold higher specific cytotoxicity on the mouse fibroblast L-929 cell line than its native counterpart. In addition, significantly lowered systemic toxicity was observed in
