marycheng3 An interview with Assistant Professor Mary Cheng, on her recent work on dopamine transporter dynamics, was published by Cell Press, highlighting her recent paper paper published in Structure (see Cheng MH, Bahar I (2015) Molecular Mechanism of Dopamine Transport by Human Dopamine Transporter Structure pii: S0969-2126).


bingliuimage Dr. Bing Liu gave a poster presentation at the Postdoctoral Data & Dine Symposium on Tuesday, May 19, 2015 and won a $500 travel award. He presented his work on "TLR3-TLR7 pathway crosswalk confers innate immune memory and homeostasis."



kaitlyn and mao Two outstanding Tsinghua University Research Scholars, Feizhuo Kaitlyn Hu and Wenzhi Mao have returned to their home institutions after successfully completing extensive research, resulting in several publications in the Bahar Lab. We wish them continued success on their scientific journeys!



Anindita Dutta Award Anindita Dutta's recent award for the "Outstanding Student Researcher in the Department of Computational & Systems Biology of 2012".

Congratulations to Lidio Meireles, Ying Liu, and Lin Liu on their successful defenses!

Protein Science CoverLidio was first author on the Protein Science article that became the cover of the September 2011 issue, "Pre-existing soft modes of motion uniquely defined by native contact topology facilitate ligand binding to proteins", along with lab members Dr. Mert Gur, Dr. Ahmet Bakan, and Dr. Ivet Bahar.

Ahmet Bakan's recent PNAS paper on drug binding mechanisms vs. intrinsic changes in shape(PDF).

"Mechanisms of CFTR functional variants that impair regulated bicarbonate permeation and increase risk for pancreatitis but not for cystic fibrosis" LaRusch J et al.PLoS Genetics (2014) 10:e1004376. PMID: 2503378

Bahar research featured in winter 2014/2015 issue of Pitt Med.

"Coupled Global and Local Changes Direct Substrate Translocation by Neurotransmitter-Sodium Symporter Ortholog LeuT" Cheng MH, Bahar I (2013) Biophys J. 105:630-639. PMID: 23931311

This is a first attempt to complete the molecular description of all steps involved in LeuT transport cycle. Notably, the secondary substrate-binding site S2, the functional relevance of which has been debated, appears to stably bind an alanine only when the transporter assumes an intermediate conformer close to inward-facing state.
