The monoamine transporter (MAT) proteins responsible for the reuptake of the neurotransmitter substrates, dopamine, serotonin, and norepinephrine, are drug targets for the treatment of psychiatric disorders including depression, anxiety, and attention deficit hyperactivity disorder. Small molecules that inhibit these proteins can serve as useful therapeutic agents. However, some dopamine transporter (DAT) inhibitors, such as cocaine and methamphetamine, are highly addictive and abusable. Efforts have been made to develop small molecules that will inhibit the transporters and elucidate specific binding site interactions. This work provides knowledge of molecular interactions associated with MAT inhibitors by offering an atomistic perspective that can guide …

This study investigates protein nucleic acid interactions between various proteins and G quadruplex (GQ) forming messenger RNAs (mRNAs) in human neurological disorders. GQ structures are formed in DNA/RNA, when four guanine residues form planar tetrads stabilized by Hoogsteen base pairing, that stack forming a GQ structure stabilized by potassium ions. These GQ structures are targeted by the arginine-glycine-glycine (RGG) repeat domain containing RNA-binding domain.
Three RGG domain containing RNA-binding proteins, all of which have been implicated in neurological disorders, and their interactions with GQ forming mRNAs, were investigated in this study: fused in sarcoma (FUS), fragile X mental retardation protein …
