Molecular Chaperones
In most cases proteins fold spontaneously under physiological conditions and do not require any external assistance. This has become evident since the experiments on ribonuclease A conducted by Anfinsen in ‘50s and ‘60s. The list of such “successful” folders has grown since and now includes many two-state proteins catalogued in Folding & Design 3, R81. These proteins fold rapidly and reliably t...
متن کاملAging and molecular chaperones.
Chaperone function plays a key role in sequestering damaged proteins and in repairing proteotoxic damage. Chaperones are induced by environmental stress and are called as stress or heat shock proteins. Here, we summarize the current knowledge about protein damage in aged organisms, about changes in proteolytic degradation, chaperone expression and function in the aging process, as well as the i...
متن کاملMolecular Chaperones and Co-chaperones as Therapeutic Targets for Cancer
Cancer is a devastating disease that has affected millions of people, consumed tremendous efforts in the treatment/care and is incurable. Statistics from www.seer.cancer.gov show 14,140,254 people were living with cancer in 2013 in US with 1,685,210 new cases projected and 595,690 estimated deaths to occur due to cancer in 2016. Number of people surviving cancer (measured as 5-year survival rat...
متن کاملMolecular chaperones and the cytoskeleton.
Heat shock proteins, first observed because they are preferentially synthesized by organisms exposed to heat or other physiological stress, are also synthesized constitutively. These proteins are divided into several families, namely, HSP100, 90, 70, 60 (chaperonin), and the small heat shock/alpha-crystallin proteins. They enjoy a wide phylogenetic distribution and are important because they fu...
متن کاملMolecular chaperones: Pathways and networks
Some proteins synthesized by growing eukaryotic cells are transferred along unidirectional pathways of molecular chaperones until the risk of aggregation has decreased and they can be released safely. Mature proteins denatured by stress may instead be handled by chaperones acting in branched, reversible networks.
