Igs7^{tm215(CAG-ACR2*,CAG-GCaMP7s)Tasic}

The targeting vector contains (from 5' to 3') a Bxb1 attL site, a partial green fluorescent protein sequence (non-functional 500bp fragment to increase the space between the Bxb1 attB site and the insulator sequence to improve stability of the targeting vector), two copies of chicken beta-globin HS4 insulator element (to reduce reporter gene expression in absence of transactivators), a CMV-IE enhancer/chicken beta-actin/rabbit beta-globin hybrid promoter (CAG; from pCAGGS), a loxP-flanked STOP cassette (stop codons in all three reading frames linked to synthetic pA-hGHpA-PGKpA), the coding sequence of stGtACR2 (GtACR2 with targeting sequence TS and Kv2.1 and HA tag sequence), a BGH polyA, two copies of chicken beta-globin HS4 insulator element, the CAG promoter, a lox2272-flanked STOP cassette (stop codons in all three reading frames linked to synthetic pA-hGHpA-TKpA), the coding sequence of GCaMP7s (with GSG linker sequence and supersoma sequence), a BGH polyA, a PhiC31 attB site, a PGK-5'hygro cassette, an RNA splice donor, a Bxb1 attR site, SA, 3'hygro, SV40pA, and PhiC31 attP. GtACR2 is derived from the Guillardia theta anion channelrhodopsin 2 gene. (J:101977)
