    Ubiquilins (Ubqlns) are a family of ubiquitin receptors that promote the delivery of hydrophobic and aggregated ubiquitinated proteins to the proteasome for degradation.

    Jul 01, 2016 · Here we used a misfolded huntingtin exon I containing a 103-polyglutamine expansion (Htt103QP) as a model substrate for the functional study of ubiquilin proteins. We found that yeast ubiquilin mutant ( dsk2 δ) is sensitive to Htt103QP overexpression and has a defect in the formation of Htt103QP inclusion bodies.Author: Kun-Han Chuang, Fengshan Liang, Ryan Higgins, Yanchang Wang

Yeast UBL-UBA proteins have partially redundant functions ...

    In Saccharomyces cerevisiae Rad23, Ddi1 and Dsk2 are the three UBL-UBA proteins, which are hypothesized to shuttle ubiquitinated substrates to the proteasome for degradation [6-11] due to their ability to interact with the proteasome through their UBL domains [12-15] as well as with ubiquitin and polyubiquitinated substrates through their UBA domains [7,8,16-18].Author: Laura A Díaz-Martínez, Yang Kang, Kylie J Walters, Duncan J Clarke

Pupylation vs. Ubiquitylation: Tagging for Proteasome ...

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3647454/
    Apr 01, 2010 · The best-studied protein modification targeting proteins for degradation in eukaryotes is ubiquitin. Ubiquitin is a highly conserved, 76 amino acid protein that covalently attaches to substrate lysines though its C-terminal di-glycine (GG) motif.Author: Kristin E. Burns, K. Heran Darwin
