The UCS family of myosin chaperones.
The canonical UCS (UNC-45/Cro1/She4p) protein, Caenorhabditis elegans UNC-45, was one of the earliest molecules to be shown genetically to be necessary for sarcomere assembly. Genetic analyses of homologues in several fungal species indicate that the conserved UCS domain functionally interacts with conventional type II and unconventional type V myosins. In C. elegans and other invertebrate spec...
متن کاملRng3, a member of the UCS family of myosin co-chaperones, associates with myosin heavy chains cotranslationally.
The production of functional myosin heavy chains in many eukaryotic organisms requires the function of proteins containing UCS domains (UNC-45/CRO1/She4), which bind to the myosin head domain and stimulate its folding. UCS proteins are essential for myosin-related functions such as muscle formation, RNA localization and cytokinesis. Here, we show that the Schizosaccharomyces pombe UCS protein R...
متن کاملExtracellular chaperones.
The maintenance of the levels and correct folding state of proteins (proteostasis) is a fundamental prerequisite for life. Life has evolved complex mechanisms to maintain proteostasis and many of these that operate inside cells are now well understood. The same cannot yet be said of corresponding processes in extracellular fluids of the human body, where inappropriate protein aggregation is kno...

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 کاملSpecialized chaperones
A n interphase meeting between X chromosomes, revealed by Na Xu, Chia-Lun Tsai, and Jeannie Lee (Harvard Medical School, Boston, MA), ensures that one and only one is silenced. Silencing of one of the two X chromosomes in a female somatic cell brings the gene dosage level down to that of male cells. Inactivation is controlled by several noncoding RNAs transcribed from, and acting in cis upon, t...
