New article on hormones interacting with neurotransmitter receptors in PLOS ONE

ReseT3 interactions with GABA(A) receptorarch from our collaboration with Dr. Joe Martin’s group here at Rutgers-Camden is now published in PLOS ONE: “Interactions of  L-3,5,3′-triiodothyronine, Allopregnanolone, and Ivermectin with the GABA(A) receptor: Evidence for Overlapping Intersubunit Binding Modes” by T. Westergard, R. Salari, J. V. Martin, and G. Brannigan.

In this paper, we use experimental and computational methods to investigate the likelihood that thyroid hormone T3 and the neurosteroid allopregnanolone bind to intersubunit binding site(s) in the transmembrane domain of the GABA(A) receptor.  We also use results from Molecular Dynamics Simulation to propose an explanation for why mutagenesis studies are so frequently inconclusive for GABA(A) pharmacology.

New Article in Structure

Figure 2 from Carswell et al, Structure, 2015

Research from our collaboration with the Baenziger group has been published in Structure: “Role of the fourth transmembrane-helix in the allosteric modulation of pentameric ligand-gated ion channels” by C. Carswell,  C.M Hénault, S. Murlidaran, JPD Therien, P.F. Juranka, JA Surujballi, G. Brannigan, and J. E. Baenziger.

Postdoc Dr. Reza Salari Releases Chemplore

Chemplore is an easy to use, convenient front end for PubChem and the PDB.  Given a compound name or PDBID, Chemplore provides structures in a number of different representations, including a rotatable 3D viewer and 2D/3D sdf.  Several other features make getting useful information on small molecule(s) straightforward and quick.  Dr. Brannigan’s favorite feature is “Compare” : try comparing 4 inhaled anesthetics.
