It has been found that the development of schizophrenia and some other psychiatric disorders is related to defects in the normal functioning of Disrupted-In-Schizophrenia 1 (DISC1). It is a large-sized protein containing 855 residues and acts as an active hub at the core of many interactions with various proteins. On the other hand, NudE Neurodevelopment Protein 1 Like 1 (Ndel1) plays a role in nervous system development via interaction with the DISC1. It was shown that some point mutations on DISC1 have clinical implications. In line with these reports, here we have used the NMR structure of the wild-type (WT) C-terminal tail of DISC1 in complex with the N-terminal fragment of Ndel1, and have constructed the three-dimensional structures of L62Q and L29Q mutants, as the pathologic variants of the complex. The time-dependent interaction of DISC1 with Ndel1 in the WT complex and mutants was simulated by performing molecular dynamics (MD) simulation using programs in the GROMACS package. It was found that the flexibility of residues in some regions of the protein chains increases, and secondary structural changes from ordered toward unordered one leads to destabilizing of the complex in mutants. Destabilization of the complex upon substitution of Leu by Gln was also confirmed by analysis of the contact map plot. Communicated by Ramaswamy H. Sarma
