pDsRed2-Peroxi encodes a fusion of Discosoma sp. red fluorescent protein (DsRed2) and the peroxisomal targeting signal 1 (PTS1). The PTS1 sequence is fused to the 3′-end of DsRed2 and encodes the tripeptide SKL, which targets the fusion protein to the matrix of peroxisomes. DsRed2 is human codon-optimized for high expression in mammalian cells. pDsRed2-Peroxi is designed for fluorescent labeling of peroxisomes.
