摘要:
This invention provides tandem fluorescent protein construct including a donor fluorescent protein moiety, an acceptor fluorescent protein moiety and a linker moiety that couples the donor and acceptor moieties. The donor and acceptor moieties exhibit fluorescence resonance energy transfer which is eliminated upon cleavage. The constructs are useful in enzymatic assays.

摘要:
The present invention includes a fluorescent compound that can detect an activity, such as an enzymatic activity, and exhibits quenching. The fluorescent compound can include a fluorescent protein, such as an Aequorea-related green fluorescent protein. The fluorescent compound can include a substrate site for an enzymatic activity such as a kinase activity, a phosphatase activity, a protease activity, and a glycosylase activity. The fluorescent compound of the present invention can be used to detect such enzymatic activities in samples, such as biological samples, including cells. The present invention also includes nucleic acids that encode the fluorescent compounds of the present inventions, and cells that include such nucleic acids or fluorescent compounds.
摘要:
The invention is directed to a method of preparing a nucleic acid sequence with a modified splice site usage profile, which employs the use of a nucleic acid sequence comprising a cryptic splice donor site. The invention also provides a method of producing an alternate form of an RNA molecule encoded by a nucleic acid sequence, which nucleic acid sequence comprises a cryptic splice donor site, a heterologous nucleic acid sequence, and a splice acceptor site.
