Ybx1^{Gt(W094B04)Wrst}

Trapped gene association determined by genome coordinate overlap and strand. Exon 7 of the gene locus was interrupted by insertion of the gene trapping vector pT1betageo. The vector fusion gene's chain termination signal results in loss of all downstream sequences. While the mutant allele was detected in spermatozoa from highly chimeric mice, no embryos carrying the mutant allele were detected. This allele may have a dominant negative effect.
