Control of mRNA stability in eukaryotes.
mRNA turnover plays a key role in the control of gene expression. Recent work has shown that proteins involved in mRNA turnover are located in multicomponent complexes which are tightly regulated. The control of mRNA stability is also intimately linked with translational processes. This article reviews the pathways and enzymes that control mRNA turnover in eukaryotic cells and discusses their m...
متن کاملmRNA stability and control of cell proliferation.
Most of the studies on cell proliferation examine the control of gene expression by specific transcription factors that act on transcriptional initiation. In the last few years, it became evident that mRNA stability/turnover provides an important mechanism for post-transcriptional control of gene expression. In eukaryotes, mRNAs are mainly degraded after deadenylation by decapping and exosome p...
متن کاملAssembly of the Sos1-Grb2-Gab1 ternary signaling complex is under allosteric control.
Allostery has evolved as a form of local communication between interacting protein partners allowing them to quickly sense changes in their immediate vicinity in response to external cues. Herein, using isothermal titration calorimetry (ITC) in conjunction with circular dichroism (CD) and macromolecular modeling (MM), we show that the binding of Grb2 adaptor--a key signaling molecule involved i...
متن کاملSOS1 expression in Salicornia
The plasma membrane Na + /H + -antiporter SOS1 is essential for salt tolerance in plants. In Chapter 4, we observed a ten-fold higher constitutive expression of SOS1 in the highly salt tolerant salt-accumulating halophyte Salicornia dolichostachya in comparison with a lower inducible SOS1 expression in its glycophytic family member Spinacia oleracea. The objective of this study was to investiga...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
