YY1 Is Required for Posttranscriptional Stability of SOX2 and OCT4 Proteins.

ABSTRACT: Yinyang1 (YY1) participates in protein-DNA, protein-RNA, and protein-protein interactions and regulates developmental processes and disease mechanisms. YY1 interactions regulate a range of important biological functions, including oocyte maturation, epithelial to mesenchymal transition, and vascular endothelial growth factor (VEGF) signaling. We tested the hypothesis that YY1 is required for inner cell mass (ICM) lineage commitment during preimplantation development. In this study, we document gene expression patterns and protein localization of key transcription factors in Yy1 global, tissue-specific, and dsRNA-mediated knockout/down embryos. YY1 protein was found in cells of preimplantation and peri-implantation embryos, and adult tissues where two isoforms are observed. In the absence o
