We do not yet know the reason for this disparity between gene expression and enzyme activity but it should be noted that the levels of transcripts and proteins in a cell are determined by several factors, like the rate of transcription initiation, mRNA stability, efficiency of translation, and protein stability and modifications.
Protein phosphorylation influences the activity of transcription factors through diverse mechanisms, such as modulation of their nucleo-cytoplasmic distributions, DNA-binding properties, and protein stabilities and modification of their interactions with other regulatory proteins [ 33, 38, 39].
The influence of experimental variables on process stability and Al2O3 modification and structure was investigated.
As a novel bio-recognition element, aptamers, single strand oligonucleotides, with the superiority including strong affinity, high stability, and easy modification of functional groups, have the potential designing highly sensitive, selective and structure switchable sensing assays [12 14].
Deamination of Asn at position 24 might be responsible for degradation of VIP derivative, and stability and chemical modification studies led us to the successful development of novel VIP derivatives with higher stability and biological functions.
Benzimidazole-based iridium (III) [Ir III)] complexes as emissive phosphors in organic light-emitting diodes (OLEDs) have received extensive investigation due to their good electron mobility, excellent thermal stability and flexible modification ability.
Colloidal titanium dioxide and zinc oxide nanoparticulates were incorporated into the novel silane/siloxane o/w emulsions and characteristics of such systems were then assessed in terms of thermal stability and rheological modification.
This active interplay between SUMOylation and ubiquitylation is likely to dictate the degree of VHL stability, and SUMO1 modification of VHL will have a major impact on its inactivity as a ubiquitin ligase.
There is also a functional link of ING proteins to p53 in senescence as regulators of p53 protein stability and posttranslational modification [ 2, 20].
