Cbx4 is a member of Polycomb complexes, and its expression is closely related to the development of the heart and immune system. In this study, we will using a mouse model to investigate the function of Cbx4 in thymus development. First, Cbx4 whole-body knockout mice will be constructed, and their thymus will be monitored to understand the effect of Cbx4 on thymus development. Secondly, Cbx4 will be overexpressed in mouse T cells and thymocytes to observe its function. Finally, protein mass spectrometry will be used to identify the target genes of Cbx4 binding and explore its role in thymus development. Through this research, we can better understand the role of Polycomb complexes in thymus development, which is helpful for understanding the role of these proteins in the development and disease of the immune system.Keywords:精品文档---下载后可任意编辑Polycomb proteins; Cbx4; thymus development; mouse model; target gene.
