Thesis On Ubiquitin

It is currently unknown if this motif regulates Ch AT function.

The effects of HSP inhibition were greatest for mutant P17A/P19A- and V18M-Ch AT. Lastly, inhibition of the endoplasmic reticulum (ER)- and HSP-associated co-chaperone Cdc48/p97/Valosin-containing protein (VCP) prevented the degradation of ubiquitinated Ch AT.

Together my results identify novel mechanisms for the functional regulation of wild-type and CMS-related mutant Ch AT by multiple molecular chaperones and the ubiquitin-proteasome system that, importantly, may have broader implications for Ch AT function during cellular stress and disease.

We predict that, contrary to the AFM experiments, an additional unfolding peak would occur at the end-to-end $\Delta R \approx 1.5 $nm in the force-extension curve.

Our study reveals the important role of non-native interactions which are responsible for a peak located at $\Delta R \approx 22 $nm.

Defects in ubiquitin-dependent proteolysis have been shown to result in a variety of human diseases, including cancer, neurodegenerative diseases, and metabolic disorders.

The SCF (Skp1-Cullin-F-box-Hrt1) complex is a heteromeric ubiquitin ligase that multiubiquitinates proteins important for signal transduction and cell cycle progression.

A technology was developed known as Protac (Proteolysis Targeting Chimeric Molecule), that acts as a bridge, bringing together the SCF ubiquitin ligase with a protein target, resulting in its ubiquitination and degradation.

The Protac contains a peptide moiety at one end that is recognized by SCF that is chemically linked to the binding partner or ligand of the target protein.

    Ubiquitin was eluted at 45% of the elution buffer. After wards, the fractions were run on a gel to determine the ones containing ubiquitin. The fractions containing ubiquitin were collected together and concentrated to 1 mL using Amicon Ultra filtration flasks pore size 3 kDa and its purity was again determined using 15% SDS-PAGE gel.…

    In the absence of ubiquitin activation, these proteasome complexes are depleted of ubiquitin conjugates and the ubiquitin-binding receptor proteins Rad23 and Dsk2. Binding of Rad23 to these proteasomes in vitro is enhanced by addition of either free or substrate-linked ubiquitin chains.…

    The ubiquitin-proteasome system is the major pathway by which the cell targets proteins for degradation in a specific manner. Ubiquitination is a process in which ubiquitin is covalently conjugated to proteins via an enzymatic cascade composed of an E1 activating enzyme, an E2 conjugating enzyme and an E3 ubiquitin ligase.…

    The stability of the p53 protein is primarily regulated through ubiquitin mediated proteolysis, and there are multiple ubiquitin ligases targeting p53 for degradation. Here we are able to address the question of functional redundancy by indicating that Pirh2 can target serine 15 phosphorylated p53 which is reported to not be regulated by Mdm2.…
