Protein Targeting Inside Eukaryotic Cells

Protein targeting helps eukaryotic cells send proteins to the right organelle. Each membrane-bound organelle has its own protein needs, so proteins must be sorted after they are made. This process is called protein sorting.

Protein sorting happens in two main ways: signal-based sorting and vesicl...

Protein sorting occurs during translation or after protein synthesis by two distinct processes: signal-based sorting and vesicle-based trafficking. Signal-based sorting employs two modes of transport: gated transport and protein translocation.

Nuclear proteins are actively transported from the cytosol to the nucleus via the nuclear pore c...
