Epididymis-specific receptor protein and its use

摘要

A mammalian epididymis-specific receptor protein having a 1038 amino acid sequence (given in the specification), and derivatives and fragments of the protein with the same biological activity and/or immunogenicity, are new. Also claimed are: (1) DNA sequences encoding for the protein, its derivatives or fragments as above; (2) vector molecules containing one or more DNA sequences as above inserted so as to maintain replicability in suitable host cells; (3) prokaryotic or eukaryotic host cells containing the vector molecules; and (4) antibodies specific for proteins or polypeptides as above.
