NKX1-2 is a transcriptional regulator that functions as a master controller of multiple developmental processes. In pre-implantation embryo development, NKX1-2 serves as a Wnt-dependent master regulator essential for proper embryogenesis, controlling ribosome biogenesis, RNA translation, and nucleolus structure 1. Loss of NKX1-2 function leads to chromosome 10, reduced blastomere numbers, and impaired blastocoel formation, ultimately causing developmental arrest 1. The protein plays a crucial role in cell fate determination, promoting adipogenesis in mesenchymal stem cells while inhibiting osteoblast differentiation by suppressing the antiadipogenic factor NR2F2 2. NKX1-2 expression is induced during 3T3-L1 adipocyte differentiation, and its knockdown almost completely blocks this process 2. In liver regeneration, NKX1-2 is downstream of lncHand2 and triggers c-Met signaling pathway activation 3. The gene also marks neuromesodermal progenitor cells and is involved in human primordial germ cell-like cell specification 45. Additionally, NKX1-2 shows expression in the central nervous system during development and its methylation status can be influenced by environmental temperature 67.
