RUNX2 meaning in Academic & Science ?

Runt-related transcription factor 2 (RUNX2) also known as core-binding factor subunit alpha-1 (CBF-alpha-1) is a protein that in humans is encoded by the RUNX2 gene. RUNX2 is a key transcription factor associated with osteoblast differentiation.

It has also been suggested that Runx2 plays a cell proliferation regulatory role in cell cycle entry and exit in osteoblasts, as well as endothelial cells. Runx2 suppresses pre-osteoblast proliferation by affecting cell cycle progression in the G1 phase. In osteoblasts, the levels of Runx2 is highest in G1 phase and is lowest in S, G2, and M. The comprehensive cell cycle regulatory mechanisms that Runx2 may play are still unknown, although it is generally accepted that the varying activity and levels of Runx2 throughout the cell cycle contribute to cell cycle entry and exit, as well as cell cycle progression. These functions are especially important when discussing bone cancer, particularly osteosarcoma development, that can be attributed to aberrant cell proliferation control.
