Abstract:

PP5715 is a putative tumor suppressor gene that encodes a protein of 199 amino acids. Expression of PP5715 in E. coli was mainly as inclusion bodies. The recombinant protein was purified by a NTA-Ni2+ affinity column, refolded by dialysis, and shown to suppress growth of two human hepatocellular carcinoma cell lines using the MTT assay or the clonogenic assays. Computer analysis and fusion expression of PP5175 and GFP showed that PP5715 may be a secretory protein. It may bind to receptors on the membrane surface and thus induce regulation of cell growth. These preliminary results suggest that protein PP5715 may be a new tumor suppressor with growth inhibition effects on hepatocellular carcinoma cells.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
