Modulation of intracellular chloride concentration ([Cl(-)](i)) plays a fundamental role in cell volume regulation and neuronal response to GABA. Cl(-) exit via K-Cl cotransporters (KCCs) is a major determinant of [Cl(-)](I); however, mechanisms governing KCC activities are poorly understood. We identified two sites in KCC3 that are rapidly dephosphorylated(More)
Virions are thought to contain all the essential proteins that govern virus egress from the host cell and initiation of replication in the target cell. It has been known for some time that influenza virions contain nine viral proteins; however, analyses of other enveloped viruses have revealed that proteins from the host cell can also be detected in(More)
NKCC1 and KCC2, related cation-chloride cotransporters (CCC), regulate cell volume and γ-aminobutyric acid (GABA)-ergic neurotranmission by modulating the intracellular concentration of chloride [Cl(-)]. These CCCs are oppositely regulated by serine-threonine phosphorylation, which activates NKCC1 but inhibits KCC2. The kinase(s) that performs this function(More)
The actin-based motility of the intracellular pathogen Listeria monocytogenes relies on ActA, a bacterial factor with a structural domain allowing it to mimic the actin nucleation-promoting activity of host cell proteins of the WASP/WAVE family. Here, we used an RNAi-based genetic approach in combination with computer-assisted image analysis to investigate(More)
We report a significantly-enhanced bioinformatics suite and database for proteomics research called Yale Protein Expression Database (YPED) that is used by investigators at more than 300 institutions worldwide. YPED meets the data management, archival, and analysis needs of a high-throughput mass spectrometry-based proteomics research ranging from a single(More)
UNLABELLED Successful addiction treatment depends on maintaining long-term abstinence, making relapse prevention an essential therapeutic goal. However, exposure to environmental cues associated with drug use often thwarts abstinence efforts by triggering drug using memories that drive craving and relapse. We sought to develop a dual approach for weakening(More)
Biochemistry. Today, the Keck Lab provides more than 175 state-of-the-art genomic, pro-teomic, biostatistical, bioinformatics, and high performance computing technologies to hundreds of Yale and non-Yale investigators whose research programs otherwise may not benefit from the highly sophisticated and expensive instrumentation upon which biological and(More)
Isotope-coded affinity tags (ICAT) is a labeling technique that provides insights into quantitative molecular changes. In this paper, we propose a new protocol to identify and analyze ICAT labeled peak pairs in high-resolution LC-MS data. Our major contributions are: (1) we use isotope distance constraint, ICAT distance constraint, and LC-span constraint to(More)
