pECFP-MEM载体简介：

pECFP-Mem encodes a fusion protein consisting of the N-terminal 20 amino acids of neuromodulin, also called GAP-43 (1), and a cyan fluorescent variant of the enhanced green fluorescent protein (EGFP). The neuromodulin fragment contains a signal for posttranslational palmitoylation of cysteines 3 and 4 that targets ECFP to cellular membranes. The ECFP gene contains amino acid substitutions that give ECFP fluorescence excitation (major peak at 433 nm and a minor peak at 453 nm) and emission (major peak at 475 nm and a minor peak at 501 nm) spectra similar to other cyan emission variants (2, 3). These substitutions also enhance the brightness and solubility of the protein (2, 4, 5). In addition to the chromophore mutations, ECFP contains over 190 silent mutations that create an open reading frame comprised almost entirely of preferred human codons (6, 7). Furthermore, upstream sequences flanking the ECFP-Mem fusion protein have been converted to a Kozak consensus translation initiation site (8). These changes increase the translational efficiency of the fusion protein and consequently its expression in mammalian cells.

Expression of ECFP-Mem is driven by the immediate early promoter of CMV (P_{CMV IE}). The vector contains an SV40 origin of replication and a neomycin resistance (Neo^r) gene for selection in mammalian cells. A bacterial promoter upstream of this cassette (P) expresses kanamycin resistance in E. coli. The vector backbone also provides a pUC19 origin of replication for propagation in E. coli and an f1 origin for single-stranded DNA production.
