Fluorescent protein and gene encoding the same
View Patent ↗The present invention provides a novel fluorescent protein the wavelength of the maximum of the fluorescence of which exists in a wavelength side longer than 510 nm, and which exhibits yellow fluorescence or yellowish green fluorescence and can be expressed in a heterogeneous cell, and a gene encoding the same, wherein the fluorescent protein has an amino acid sequence as set forth in SEQ ID NO: 1 and it is a fluorescent protein derived from a copepod taxonomically classified to Chiridius Poppei.
1. A fluorescent protein from a copepod taxonomically classified to Chiridius Poppei , comprising the full-length amino acid sequence of SEQ ID No: 1, the fluorescent protein being recombinantly expressed,
wherein the fluorescent protein has a fluorescence spectrum having a maximum peak with a wavelength of 518 nm and an excitation spectrum having a maximum peak of wavelength of 507 nm,
wherein a fluorescence performance of the fluorescent protein is due to the fluorescent core of the fluorescent protein, which fluorescent core is post-translationally formed from G 55 Y 56 G 57 tripeptide site in SEQ ID NO: 1 through cyclization and subsequent oxidation.
