Cold-Shock Response in Escherichia coli 193 Cold Shock Response in Escherichia coli
Sensing a sudden change of the growth temperature, all living organisms produce heat shock proteins or cold shock proteins to adapt to a given temperature. In a heat shock response, the heat shock sigma factor plays a major role in the induction of heat shock proteins including molecular chaperones and proteases, which are well-conserved from bacteria to human. In contrast, no such a sigma fact...
متن کاملMajor cold shock protein of Escherichia coli.
When exponentially growing Escherichia coli cell cultures were transferred from 37 degrees C to 10 degrees C or 15 degrees C, the production of a 7.4-kDa cytoplasmic protein (CS7.4) was prominently induced. The rate of CS7.4 production reached 13% of total protein synthesis within 1-1.5 hr after a shift to 10 degrees C and subsequently dropped to a lower basal level. Regulation of CS7.4 express...

متن کاملTagging and Enriching Proteins Enables Cell-Specific Proteomics
Cell-specific proteomics in multicellular systems and whole animals is a promising approach to understand the differentiated functions of cells and tissues. Here, we extend our stochastic orthogonal recoding of translation (SORT) approach for the co-translational tagging of proteomes with a cyclopropene-containing amino acid in response to diverse codons in genetically targeted cells, and creat...
متن کاملCold Shock Proteins Mediate GN with Mesangioproliferation.
DNA binding protein A (DbpA) is a member of the human cold shock domain-containing protein superfamily, with known functions in cell proliferation, differentiation, and stress responses. DbpA mediates tight junction-associated activities in tubular epithelial cells, but the function of DbpA in mesangial cells is unknown. Here, we found DbpA protein expression restricted to vascular smooth muscl...
