Bcl-XL

Bcl-XL is a protein that helps cells survive by preventing their programmed death, known as apoptosis. It is part of the Bcl-2 family of proteins and functions by blocking signals that trigger cell death, thus supporting cell longevity. Bcl-XL is especially important in protecting healthy cells from unnecessary or accidental death, and it also plays a role in cancer progression by helping cancer cells evade apoptosis. Maintaining the balance of these proteins is crucial for normal cell function and health, influencing processes like development, immune response, and tissue maintenance.
