title: [Generation of Ayu17-449 gene knockout mice by gene trapping].
abstract: We report the generation of Ayu17-449 gene knockout mice in an effort to facilitate studies of its function during mouse development, A special gene trapping vector was transfected into mouse ES cells. The clone with the trapped gene trap was identified by 5' RACE and Southern blot analysis. Ayu17-449 trapped mice were then generated by using this ES clone. In addition, the expression of Ayu17-449 in this mutant line was analyzed with Northern blot. Results showed that in these mutant mice, the trapping vector was located upstream of the Ayu17-449 initiation site, and as a result, the transcription of Ayu17-449 gene was inhibited. Ayu17-449 trapped mice are a useful tool for the analysis of Ayu17-449 gene function in mouse development.
