[Answer] How do master regulatory genes function in cell differentiation?

Answer: They produce proteins that act as transcription factors to produce proteins specific to the function of the particular cell type. They are often capable of changing some fully differentiated cells of different types into their particular cell type. They may produce proteins that stimulate production of more of the master regulatory gene. The transcription factors they produce coordinately control related genes.
How do master regulatory genes function in cell differentiation?

In genetics a master regulator is a gene at the top of a gene regulation hierarchy particularly in regulatory pathways related to cell fate and differentiation .. Examples. Most genes considered master regulators code for transcription factor proteins which in turn alter the expression of downstream genes in the pathway. Canonical examples of master regulators include Oct-4 (also called …

Cellular differentiation is the process in which a cell changes from one cell type to another. Usually the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. Differentiation continues in adulthood as adult stem cells divide and create …

In addition to being the master regulator of osteoblast differentiation Runx2 has also been shown to play several roles in cell cycle regulation. This is due in part to the fact that Runx2 interacts with many cellular proliferation genes on a transcription level such as c-Myb and C/EBP [5] as well as p53 / [7] These functions are critical …
