Prediction of dual protein targeting to plant organelles

Prediction of dual protein targeting to plant organelles.

* Dual targeting of proteins to more than one subcellular localization has been found in animals, in fungi and in plants. In the latter, ambiguous N-terminal targeting signals have been described that result in the protein being located in both mitochondria and plastids. We have developed ambiguous targeting predictor (ATP), a machine-learning implementation that classifies such ambiguous targe...

Role of protein phosphorylation in preprotein targeting to plant organelles

Targeting a heterologous protein to multiple plant organelles via rationally designed 5′ mRNA tags

BACKGROUND Plant bioengineers require simple genetic devices for predictable localization of heterologous proteins to multiple subcellular compartments. RESULTS We designed novel hybrid signal sequences for multiple-compartment localization and characterize their function when fused to GFP in Nicotiana benthamiana leaf tissue. TriTag-1 and TriTag-2 use alternative splicing to generate differe...

Protein targeting to subcellular organelles via MRNA localization.

Cells have complex membranous organelles for the compartmentalization and the regulation of most intracellular processes. Organelle biogenesis and maintenance requires newly synthesized proteins, each of which needs to go from the ribosome translating its mRNA to the correct membrane for insertion or transclocation to an a organellar subcompartment. Decades of research have revealed how protein...

Dopamine-conjugated apoferritin protein nanocage for the dual-targeting delivery of epirubicin

Objective(s): Nanocarriers are drug delivery vehicles, which have attracted the attention of researchers in recent years, particularly in cancer treatment. The encapsulation of anticancer drugs using protein nanocages is considered to be an optimal approach to reducing drug side-effects and increasing the bioavailability of anticancer drugs. Epirubicin (EPR) is an active chemotherapeutic medica...
