TgTn(sb-Tyr)2161BOve

A Sleeping Beauty (SB) transposon transgenic approach was used to generate these mice. The pT2-BART3 transposon vector used here has (from 5' to 3') an inverted repeat/direct repeat sequence (IR/DR; the SB transposon recognition site [280 bp]), an AD2 splice acceptor and polyA sequence, the tyrosinase minigene TyBS, a loxP site, a polyA sequence, a Hox9c splice acceptor, and right IR/DR (280 bp). The IR/DR sequences are outward-facing. The 4.1 kb tyrosinase minigene (TyBS) contains the tyrosinase upstream regulatory sequences (2.1 kbp from the BALB/c tyrosinase promoter and the first 65 bp of exon 1), followed by the C57BL/6-derived Tyrs-J cDNA sequence (1.9 kbp including cysteine at amino acid 103, glycine at amino acid 346, and the stop codon with polyA signal).
