The Involvement Of Ubiquitin In Med13 Cyclin C Degradation Following Cellular Stress, Ayesha Gurnani, Brittany Friedson, Katrina Cooper

Rowan-Virtua Research Day

The Cdk8 Kinase Module is a dissociable regulator of cellular stress response genes, with degradation of its components Med13 and cyclin C eventually determining cell fate decisions such as engaging cell survival or cell death mechanisms. We aimed to explore the roles of ubiquitin in degradation of the Cdk8 Kinase Module following nitrogen starvation, with respect to the potential involvement of deubiquitinating enzyme Doa4, lysine linkage at position K63, and E2 ubiquitin conjugating enzymes Ubc4 and Ubc5. We utilized Western blot analysis to observe nitrogen starvation-induced degradation of Med13-HA in wild-type, doa4 mutant, and K63R yeast strains; degradation of cyclin …

Elucidating The Role Of Hausp Ubiquitin Like Domains In The Catalytic Function Of Usp7, Anuj Patel, Nicole Davis, Andrew Mesecar

The Summer Undergraduate Research Fellowship (SURF) Symposium

Ubiquitin specific proteases (USPs) are a class of enzymes involved in myriad cellular processes. One USP of great interest due to its oncogenic properties is USP7. In normal conditions USP7 is closely regulated due to its responsibility for destabilizing the tumor suppressor, p53, through the deubiquitination of MDM2. In multiple myeloma cases, it appears the regulation of USP7 subsides, as it is largely overexpressed, leading to the inappropriate degradation of p53. Inhibition of USP7 could, therefore, prove a viable target for cancer therapy. A greater understanding of USP7’s function and structure can lead to more insight into how this enzyme …


Regulation Of The Ampa Glutamate Receptor Homolog Glr-1 At The Endoplasmic Reticulum In C. Elegans., Sam Witus, Lina Dahlberg May 2015

Regulation Of The Ampa Glutamate Receptor Homolog Glr-1 At The Endoplasmic Reticulum In C. Elegans., Sam Witus, Lina Dahlberg

Scholars Week

In C. elegans, the glutamate receptor GLR-1 functions in the nervous system to decode environmental stimuli and sensory experiences, and to regulate locomotion and the formation of long-term memory. C. elegans GLR-1 is homologous to mammalian glutamate receptors, and we can use this simple organism as a system to better understand the life cycle of human receptors (1). Because GLR-1 is a membrane protein, it is first assembled in the interior of a neuron, and then it is transported to the membrane at the surface of the cell so that it can receive chemical signals (glutamate) from the environment. Currently, …
