CDKN1B

CDKN1B is a special kind of protein that helps your cells know when to grow and divide. It's like a traffic light for your cells, telling them when they can go and when they need to stop.

Sometimes, your cells grow and divide too much, which can be dangerous. CDKN1B helps to slow down this process and keep your cells from growing and dividing too much.

Think of it like this: if you're playing with blocks, you might want to build a big tower, but you need to make sure you have enough blocks and that the tower is stable. CDKN1B is like a parent who tells you when you have enough blocks and when it's time to stop building.

Overall, CDKN1B is an important protein that helps keep your cells healthy and functioning properly. By controlling when cells grow and divide, it helps keep your body running smoothly and protects you from harm.
