Cardiac 20S proteasome function is modulated by associating partners

Published in Proteomics Weekly, October 23rd, 2006

The function of cardiac 20S proteasomes is modulated by associating partners and perhaps regulated by phosphorylation.

According to scientists in the United States, "Our recent studies have provided a proteomic blueprint of the 26S proteasome complexes in the heart, among which 20S proteasomes were found to contain cylinder-shaped structures consisting of both alpha and beta subunits. These proteasomes exhibit a number of features unique to the myocardium, including striking differences in post-translational modifications (PTMs) of individual subunits and novel PTMs that have not been previously reported."

"To date, mechanisms contributing to the...
