摘要
The present invention refers to a fluorescent fusion polypeptide capable of changing its localization within the cell from the cell cytoplasmic membrane to the retention vesicles, upon an increase in the concentration of second messengers within the cell cytoplasm, comprising a membrane localization peptide, a second messenger transduction protein binding peptide, a reticulum retention signal and a fluorescent peptide wherein: a. the membrane localization peptide is located at the N-terminus of the fluorescent fusion polypeptide and is physically bound, optionally through a linker, to the fluorescent peptide, which in turn is physically bound, optionally through a linker, to the second messenger transduction protein binding peptide; and b. the second messenger transduction protein binding peptide is physically bound, optionally through a linker, to the reticulum retention signal, which in turn is located at the C-terminus of the fluorescent fusion polypeptide.
