Method of identifying transmembrane protein-interacting compounds

摘要

A method for screening a candidate compound for its ability to interact with at least one transmembrane protein comprising:
transfecting a cell with at least one nucleotide sequence encoding a protein comprising a transmembrane protein containing at least one nuclear localisation sequence (NLS) and a detectable moiety and permitting expression of the encoded protein in the cell;
contacting the cell with a candidate compound; and
determining the distribution of the expressed protein in the cell by detecting the distribution of the detectable moiety in the cell;
wherein detection of an altered distribution of the detectable moiety in the cell relative to the distribution of the detectable moiety in a control cell not contacted with the candidate compound indicates that the compound interacts with the transmembrane protein, and
wherein the wild type transmembrane protein contains an NLS.
