Regulation Of G Protein Signaling By Goloco Motif Containing Proteins, Peishen Zhao
Regulation Of G Protein Signaling By Goloco Motif Containing Proteins, Peishen Zhao
Electronic Thesis and Dissertation Repository
Signal transduction via heterotrimeric G proteins in response to transmembrane G protein-coupled receptors plays a central aspect in how cells integrate extracellular stimuli and produce biological responses. In addition to receptor-mediated activation of heterotrimeric G proteins, during the last few decades, accessory proteins have been found to regulate G protein activity via different mechanisms. Several proteins have been identified that contain multiple G protein regulatory domains. Using various molecular and biochemical approaches, we have characterized the effects of two such proteins, G18 and RGS14, on G protein activity. Both proteins contain a second G protein binding domain in addition to …

One of the critical functions of human adenovirus (hAd) early region 1A (E1A) protein is to activate transcription of the early viral genes. The largest isoform of E1A contains a unique region termed conserved region 3 (CR3), which includes a Cysteine-4 (C4) zinc finger domain. This region activates viral gene expression by interacting with and recruiting cellular transcription machinery to the regulatory regions of early viral genes. Although this process has been studied at length with hAd type 5 E1A, far less is known about how the E1A proteins from other hAd types activate transcription. There are dramatic differences in …

In 2009 approximately 2.6 million people became infected with the Human Immunodeficiency Virus (HIV). In addition to the estimated 33.3 million people currently living with the virus, this makes HIV/ AIDS an epidemic of unprecedented scale in modern times. Treatment of HIV infection requires antiretroviral agents as well as a number of other drugs such as antimicrobials. Hypersensitivity adverse drug reactions (ADRs) to a variety of drugs are common in HIV-infected individuals, but the antimicrobial Sulphamethoxazole remains a major culprit. Hypersensitivity ADRs cause significant morbidity, with the skin and liver most commonly affected and are among the top causes of …
