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 کاملMolecular gymnastics at the herpesvirus surface.
This review analyses recent structural results that provide clues about a possible molecular mechanism for the transmission of a fusogenic signal among the envelope glycoproteins of the herpes simplex virus on receptor binding by glycoprotein gD. This signal triggers the membrane-fusion machinery of the virus--contained in glycoproteins gB, gH and gL--to induce the merging of viral and cellular...
متن کاملMicrobial molecular chaperones.
Protein folding in the cell, long thought to be a spontaneous process, in fact often requires the assistance of molecular chaperones. This is thought to be largely because of the danger of incorrect folding and aggregation of proteins, which is a particular problem in the crowded environment of the cell. Molecular chaperones are involved in numerous processes in bacterial cells, including assis...
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...
