ABSTRACT:
The invention relates to luminescent proteins, nucleic acids encoding same, compositions and combinations comprising the proteins, and methods using the proteins, nucleic acids, compositions and combinations. In particular, a luminescent protein is provided comprising oncomodulin in which a salt bridge has been introduced to provide greater stability. The protein may be used as a luminescent marker in, for example, luminescent items, immunoassays, and fluorescent energy transfer assays.
