About: Eos (protein)

An Entity of Type: protein, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

EosFP is a photoactivatable green to red fluorescent protein. Its green fluorescence (516 nm) switches to red (581 nm) upon UV irradiation of ~390 nm (violet/blue light) due to a photo-induced modification resulting from a break in the peptide backbone near the chromophore. Eos was first discovered as a tetrameric protein in the stony coral Lobophyllia hemprichii. Like other fluorescent proteins, Eos allows for applications such as the tracking of fusion proteins, multicolour labelling and tracking of cell movement. Several variants of Eos have been engineered for use in specific study systems including mEos2, mEos4 and CaMPARI.

  • La EosFP è una proteina tetramerica che ha la proprietà di emettere una fluorescenza di colore dal verde al rosso; è utilizzata come marker in biologia molecolare. Lobophyllia hemprichii La EosFP fu isolata per la prima volta nella sclerattinia Lobophyllia hemprichii. Successivamente è stata clonata in Escherichia coli. È composta da 226 aminoacidi e ha una massa molecolare di 25.8 kDa. La proteina emette inizialmente ua fluorescenza verde (516 nm) che vira al rosso (581 nm) se sottoposta a irradiazione ultravioletta. (it)
