This hypomorphic gene trap demonstrates the role of Sec24d (Sec24 related gene family, member D (S. cerevisiae)) in embryonic development and protein secretion via COPII-coated vesicles.

COPII-coated vesicles carry newly-synthesized proteins from the endoplasmic reticulem to the Golgi as part of the secretory pathway. SEC23/SEC24 protein heterodimers are an essential component of the COPII coat inner layer.
This hypomorphic gene trap derived from Bay Genomics embryonic stem (ES) cell clone RRR785 disrupts paralog Sec24d (Sec24 related gene family, member D (S. cerevisiae)). Homozygotes are embryonic lethal, but survive to mid-gestation (E13.5). Heterozygotes are viable and fertile.
Bay Genomics embryonic stem (ES) cell line RRR785, derived from 129P2/OlaHsd and expressing β-geo (a fusion of β-galactosidase and neomycin phosphotransferase II), was sequenced to locate the Sec24d gene trap insertion site at position 639 of intron 20. ES cells were cultured and microinjected into blastocysts. Resultant chimeras were backcrossed to C57BL/6J for at least 15 generations by the donating laboratory.

Molecular Note | The beta-geo (lacZ and neomycin resistance cassette) containing gene trap vector inserted between exon 20 and 21. This allele is hypomorphic. |
Heterozygotes are viable and fertile, but homozygotes are not. Homozyogus embryos die sometime after embryonic day 13.5 (E13.5) and none survive to birth.

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.
