UASt sequences govern expression an inverted repeat of 770bp of Gαq cDNA sequence from a region common to all Gαq splice variants. This sequence was amplified from of the Gαq3α isoform cDNA using PCR primers: (5'-GGTACC(538)TCACGATACTAGCAGCATCCC-3') (5'-GGATCC(1314)CGGTGTAAGCGAGCGAAG-3') for the forward sequence and (5'-TCTAGA(539)GTGCTATGATCGTCGTAGGGA-3') (5'-GGATCC(1308)TTCGCTCGCTTCTCAATTCT-3') for the inverted sequence. A 12 nucleotide linker separates the forward and reverse sequences.
