Chaperonin hsp folding
WebFeb 20, 2012 · This talk focuses on one among the many chaperones; HSP60, traditionally known as in mitochondrial chaperonin, CPN 60, that as the name suggests, has a molecular weight of about 60 kiloDalton. HSP60 plays a variety of roles inside and outside cells, including not only improving quality control, folding, refolding, translocation … WebMar 1, 1989 · Similarly, the chaperonin HSP-60 has important functions in mitochondrial protein folding and -homeostasis and, hence, is essential in eukaryotic cells (42, 43). Consequently, both genes are ...

WebDec 30, 2024 · Human mitochondrial chaperonin mHsp60 is essential for mitochondrial function by assisting folding of mitochondrial proteins. Unlike the double-ring bacterial GroEL, mHsp60 exists as a heptameric ring that is unstable and dissociates to subunits. The structural dynamics has been implicated for a unique mechanism of mHsp60.
