| molecularNote | The Rosa-CAG-LSL-GCaMP3-WPRE targeting vector was designed with (from 5' to 3') a CMV-IE enhancer/chicken beta-actin/rabbit beta-globin hybrid promoter (CAG), a loxP-flanked STOP cassette, a GCaMP3 cDNA, a woodchuck hepatitis virus post-transcriptional regulatory element (WPRE; to enhance the mRNA transcript stability), a BGH polyA signal, and an FRT-flanked Neo cassette. The GCaMP3 fusion gene contains a cDNA sequence encoding the chicken smooth muscle M13 fragment of myosin light chain kinase, a circularly permutated EGFP (amino acid residues 149-238 followed by amino acid residues 1-144 (including M153K, V163A, S175G, D180Y, T203V, A206K, and V93I mutations to increase dynamic range and baseline fluorescence), and a DNA fragment encoding amino acid residues 2-148 of the rat calmodulin (modified to harbor the N60D mutation to increase the fluorescence change for small calcium transients). |
