Chimeric proteins for measuring atp concentrations in pericellular space and related screening method

摘要

The invention relates to luminescent chimeric proteins comprising a first N-terminal protein sequence, a second protein sequence and a third C-terminal protein sequence wherein: (i) said first and said third protein sequence are a leader sequence and an anchor sequence belonging to at least a receptor localized on a plasma membrane site; (ii) said second protein sequence encodes for the full-length or partial sequence of a photoprotein and is inserted in frame between said first and said third sequence (i); said chimeric protein being addressed to said plasma membrane site of the cell wherein it is expressed.
