Final answer:
Mitogens are substances that stimulate cell division and proliferation. One protein notorious for being activated by mitogens is the epidermal growth factor receptor (EGFR).
Step-by-step explanation:
Mitogens are substances that stimulate cell division and proliferation. They activate pathways that lead to the activation of mitogen-activated protein (MAP) kinase, which is essential for cell growth and differentiation.
One protein notorious for being activated by mitogens is the epidermal growth factor receptor (EGFR), which plays a key role in cell proliferation.
