| abstractText | Summary The Nlrp gene family contains 20 members and plays a pivotal role in the innate immune and reproductive systems in the mouse. During evolution, seven Nlrp4 gene copies (named from Nlrp4a to Nlrp4g). Nlrp4a-Nlrp4g have arisen that display specific or preferential ovarian expression patterns. However, the expression pattern and localization of Nlrp4g in mouse preimplantation embryo development are unknown. Here we report that Nlrp4g was highly expressed in mature oocytes and zygotes, then downregulated and not detected after the 2-cell embryo stage. NLRP4G protein remained present through the blastocyst stage and was mainly localized in the cytoplasm. Furthermore, overexpression of Nlrp4g in zygotes did not affect normal development in terms of the rate of blastocyst formation. These results provide the first evidence that NLRP4G is a maternal factor that may play essential role during zygotic genome activation in the mouse. |
