Here, in the [http://openwetware.org/wiki/Chien Chien lab] of the University of Massachusetts-Amherst, we study how [http://en.wikipedia.org/wiki/Proteolysis proteolysis] plays a large part in protein quality control. The maintenance and timely destruction of protein levels plays an important role during cell homeostasis and cell transitions/differentiation, yet much of what governs these processes has to be fully understood. | Here, in the [http://openwetware.org/wiki/Chien Chien lab] of the University of Massachusetts-Amherst, we study how [http://en.wikipedia.org/wiki/Proteolysis proteolysis] plays a large part in protein quality control.

''E. coli'' Casein lytic proteinase P (ClpP) is a double ring [http://en.wiktionary.org/wiki/tetradecamer tetradecameric] homo oligomer compartmentalized peptidase [http://www.ncbi.nlm.nih.gov/pubmed/?term=ClpP%3A+A+structurally+dynamic+protease+regulated+by+AAA%2B+proteins]. ClpP requires the use of ATP dependent regulatory elements that independently bind to ClpP in order for substrates to have access the active core [http://www.ncbi.nlm.nih.gov/pubmed/15037252][http://www.ncbi.nlm.nih.gov/pubmed/20236930][http://www.ncbi.nlm.nih.gov/pubmed/19038348]. Here, proteins that are translocated by regulatory elements into the peptidase core are cleaved into smaller amino acid chains approximately on average 6-8aa in length [http://www.ncbi.nlm.nih.gov/pubmed/16229481]. | ''E. coli'' Casein lytic proteinase P (ClpP) is a double ring [http://en.wiktionary.org/wiki/tetradecamer tetradecameric] homo oligomer compartmentalized peptidase [http://www.ncbi.nlm.nih.gov/pubmed/?term=ClpP%3A+A+structurally+dynamic+protease+regulated+by+AAA%2B+proteins].
