Glossary Anti-apoptotic protein

prevents cells from undergoing programmed cell death

An anti-apoptotic protein is a type of protein that prevents cells from undergoing apoptosis, which is a form of programmed cell death. These proteins help cells survive under stress or damage by blocking the signals that would normally trigger the cell to self-destruct. This function is crucial in maintaining healthy tissues but can also contribute to diseases like cancer, where cells avoid dying when they should.
