Phosphorylation, and its mirror process dephosphorylation, has been shown to have opposite and often contradictory effects on the ability of cargos to be transported across the nuclear envelope.
In our opinion, a functional assay of this type is superior to the use of fluorescent labels and observation of cell localization by confocal microscopy, because it is a true measure of the ability of a cargo to be delivered in a biologically relevant way, in this case to the cell nucleus.
The impβNup153 interaction significantly restricts the ability of inert cargos to diffuse across the NPC, indicating the presence of a non-specific physical barrier that cannot be explained by simple molecular crowding.
The ability of such silaffin-cargo conjugates to encapsulate the cargo molecule during silaffin-mediated silica precipitation is demonstrated.
P22 nanocages have demonstrated significant potential as a drug delivery system due to their stability, large capacity for loading with a diversity of proteins and other types of cargo, and ability to resist degradation by proteases.
Apart from the dynamic nature of the road service offering, an important reason of the dominance of road hauliers in the freight transport sector is linked to their ability to deliver certain types of cargo.
The C-17s are highly regarded throughout the Australian military for their ability to carry large amounts of cargo across long distances, and the process through which they were acquired has been identified as an example of good practice in defence procurement.
Because endocyclic delivery by cFΦR4 is limited to a heptapeptide or smaller cargos, in this study we tested the ability of cFΦR4 to deliver cargos of varying sizes and physicochemical properties attached to the Gln side chain.
The addition of E9, attached via a flexible G4S linker, did indeed substantially reduce the toxicity of R9-rGel and CPE-R9-rGel confirming in this model the observation that the electrostatic interaction between the E9 and R9 sequences when they are tethered together disables the ability of R9 to translocate cargo across lipid membranes [ 18, 26].
Just something that can handle a little city driving and frequent trips to the cottage in the warmer months, with the ability to haul a decent amount of cargo.
