Cytosol translocation
WebJan 21, 2024 · Indeed, during protein targeting to the ER, many secretory proteins fail to associate with the signal recognition particle (SRP) and can be detected in the cytosol before their translocation [99,100]. Under normal conditions in mammalian cells, the efficiency of ER translocation is not high: it may range from 60% to 95% . This implies … WebInterestingly, translocation in the reverse direction (from the nucleus to the cytosol) occurs between 40–60 min. Such reverse translocation was previously reported in the literature 41 and is due to re-inhibition of newly …

WebThe translocon (also known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes. In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or … WebDec 15, 2024 · However, compartmentalization also imposed a great challenge−the need to import proteins synthesized in the cytosol into their respective sites of function. For example, one-third of all genes encode for proteins that must be targeted and translocated into the endoplasmic reticulum (ER), which serves as the entry site to the majority of ...

WebMay 1, 2004 · In cultured primary cortical cells, cyanide produced a concentration- and time-dependent translocation of Bad from cytosol to mitochondria. Translocation occurred early in the apoptotic response, since mitochondrial Bad was detected within 1 h of cyanide treatment. Mitochondrial levels of the protein continued to increase up to 12 h post ...
WebRetro-translocation into the cytosol. Because the ubiquitin–proteasome system (UPS) is located in the cytosol, terminally misfolded proteins have to be transported from the endoplasmic reticulum back into cytoplasm.
