ABSTRACT:
A method for detecting the expression of a polypeptide in cells and for detecting the interaction between a polypeptide and cells, ex vivo or in vitro, wherein the polypeptide is selected from the group consisting of: a peptide comprising the cyt domain of the envelope protein of the human endogenous retrovirus, HERV-W; a peptide comprising amino acids 448-538 of SEQ ID NO: 1; and a peptide comprising a sequence having, for any series of 20 amino acids, at least 80% identity with amino acids 448-538 of SEQ ID NO: 1. Detection is established by the fusogenic power of the polypeptide, which is demonstrated by syncytia formation.
