mRFP1.3 Sequence

mRFP1.3 was derived from mRFP1.1 with the following mutations: M1_D6delinsMVSKGEENNMA/A225G/*224MextDELYK
amino acid numbers relative to DsRed. show relative to mRFP1.1



Because Aequorea victoria green fluorescent protein (GFP) is relatively indifferent to N- or C-terminal fusions, we eventually generated mRFP1.3 by replacing the first seven amino acids of mRFP1.1 with the corresponding residues from enhanced GFP (MVSKGEE) followed by a spacer sequence NNMA (numbered 6a–d), and appending the last seven amino acids of GFP to the C terminus. mRFP1.3, unlike its predecessors, was found to have an equivalent high level of fluorescence regardless of fusions to its N terminus.
