Abstract:
Cancer is a common cause of death worldwide. Various methods have been
introduced as efficient treatments including immunotherapy. Immunotherapy deals with an
application of functional protein to boost immune system for cancer elimination. An
immunotherapeutic protein called interleukin-18 (IL18) has caught our interest due to its
efficiency for natural killer cell and cytotoxic T lymphocyte promotion as well as metastasis
inhibition. In this work we have used molecular dynamics simulation (MD) and proteinprotein
docking to predict potential mutation point. Since IL18 binds interleukin-18 receptor
alpha (IL18a) to perform an action, the alteration of amino acid in IL18 could play a key
point. Some mutations such as N91K and N111K were selected based on a structure of IL18-
IL18Ra (PDB code 3WO3). We also chose our previously published recombinant E6K-T63A
and wild type protein (WT) as comparative controls. MD simulation with AMBER16 force
field with 310 K (37 oC) and 1 atm of IL18 in 0.15M NaCl solution was modelled to mimic
cellular environment. We found E6K-T63A and N111K provide better binding to IL18Ra,
compared to WT-IL18. It implied the higher affinity of N111K. This can lead to novel
alteration of interleukin-18 and shorten time and budget for further improvement.
