Abstract
A hook fusion protein, which includes a hook domain and at least one cytoplasmic carboxyl endoplasmic reticulum (ER) retention signal and/or at least one cytoplasmic amino terminal endoplasmic reticulum (ER) retention signal; wherein the hook fusion protein is a soluble protein that localizes in the cytoplasm. Also, a nucleic acid system for intracellular targeting control including a nucleic acid encoding a target fusion protein including a hook fusion protein, and a nucleic acid encoding a target fusion protein including a hook-binding domain; wherein the target fusion protein is a membrane protein; and wherein the hook fusion protein localizes in the ER when bound to the target fusion protein. Additionally, a vector system, viral particle system, host cell and kit include these nucleic acids. Further, the vector system, viral particle system, host cell or kit for use as a medicament, in particular for immunotherapy.
