Trim43a, Trim43b, and Trim43c: Novel mouse genes expressed specifically in mouse preimplantation embryos.


ABSTRACT: We describe the identification and characterization of Trim43a, Trim43b, and Trim43c genes, whose expression are restricted to preimplantation stages and peak at the 8-cell to morula stage. We identified a 5kb DNA fragment that covers upstream region of Trim43a as a putative promoter, which can drive the expression of mStrawberry fluorescent protein in a manner similar to endogenous Trim43 genes. Trim43 genes will be useful stage-specific markers for the study of preimplantation embryos.
