Cytoplasmic polarity
WebApr 11, 2024 · Molecules that are localized in specific cytoplasmic regions of the unfertilized egg or zygote and affect cell fate decisions by segregating into different embryonic cells and controlling distinct gene activities in these cells. In the egg, such determinants are usually maternal mRNAs and proteins. WebFeb 17, 2024 · The cytoplasmic MEX-5/6 protein, distributed homogeneously in the cytosol before symmetry breaking, becomes polarized to the anterior side, and the boundary of the MEX-5/6 polarity domain is observed in a location similar to the boundary of the anterior and posterior polarity domains (Cuenca et al. 2002; Schubert et al. 2000).

This study demonstrates that cells of 8-cell rat and mouse embryos also show a cytoplasmic polarity absent at earlier stages.
Cell polarity arises primarily through the localization of specific proteins to specific areas of the cell membrane. This localization often requires both the recruitment of cytoplasmic proteins to the cell membrane and polarized vesicle transport along cytoskeletal filaments to deliver transmembrane proteins from the golgi apparatus. Many of the molecules responsible for regulating cell polarity are conserved across cell types and throughout metazoan species. Examples include the PAR …
