MOLECULAR DYNAMICS INVESTIGATION OF ALPHACONOTOXIN SI BINDING TO nAChR

Abstract

Nicotinic Acetylcholine Receptors (nAChR) play an important role in drug discovery such as analgesics. Alpha-conotoxin SI (SI) is a 13-aminoacide peptide which exists in the venom of sea cone shell. It is crucial to investigate theinteraction of such peptides for discovering novel  drugs.  It  is  almost  impossible  to  investigate the  molecular  interactions  using experimental techniques. At this stage, computational studies such as molecular dynamics
(MD)  simulations  are  used  to  demonstrate  such  interaction  mechanisms.  A  refined structure for nAChR (Figure 1) was published by Unwin N. in 2005 [1].

We  have  carried  out  docking  and  MD  simulations  using  HADDOCK  and  NAMD  software packages respectively. We show that our MD studies  are in agreement with the previous experimental studies [2,3] which present the most possible binding sites and interaction mechanism  of  nAChR  and  SI  from  Potential  of  Mean  Force  calculations  using  a  cost-efficient approach.
