Elucidating The Role Of Hausp Ubiquitin Like Domains In The Catalytic Function Of Usp7, Anuj Patel, Nicole Davis, Andrew Mesecar Aug 2015

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 Expression Of Hmn-Sod At The Level Of The Mitochondrial Processing Of Precursor Hmn-Sod, Gary Leslie Wright Jan 1997

Regulation Of The Expression Of Hmn-Sod At The Level Of The Mitochondrial Processing Of Precursor Hmn-Sod, Gary Leslie Wright

Theses, Dissertations and Capstones

The mitochondrion imports and processes the vast majority of the proteins which comprise its structural elements and metabolic pathways. Studies in the last decade have been successful at defining the mechanism and protein machinery responsible for recognizing, importing, and processing cytosolic precursor proteins into the mature mitochondrial proteins. Little is known, however, about physiological factors which might influence or compromise mitochondrial protein processing. The objective of this work was to develop a novel approach to study mitochondrial import and assembly of precursor proteins as a process within the context of the cellular environment. To these ends we employed the baculovirus …
