The Smarcad1 gene (formerly Etl-1) was identified in close proximity to a lacZ enhancer trap integration in the mouse genome showing a specific beta-galactosidase staining pattern during development. In situ analysis revealed a widespread but not ubiquitous expression throughout development with particularly high levels in the central nervous system and epithelial cells. The amino acid sequence of the Smarcad1 protein shows strong similarity to the Drosophila brahma protein involved in the regulation of homeotic genes and to the yeast transcriptional activator protein SNF2/SWI2 as well as to the RAD54 protein and the helicase-related yeast proteins STH1 and MOT1. Smarcad1 is implicated in gene regulation and/or influencing of chromatin structure, and may be involved in gene regulating pathways during mouse development.
The 6LSN construct is one of several enhancer trap constructs designed with the lacZ reporter gene downstream of a TATA box and translation initiation codon with an attached neomycin resistance cassette. 6LSN was electroporated into 129S2/SvPas derived D3 ES cells. One of the resulting cell lines, 6028, was injected into CD1 blastocysts and gave rise to the 129S2/SvPas-Smarcad1Gt(6LSN)6028Gos mouse strain. In 1994 homozygous siblings from this strain were mated to generate embryos for cryopreservation at The Jackson Laboratory. (Gossler et al., 1989; Soininen et al., 1992.)

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
