Fibrillin

Fibrillin is a protein that forms tiny fibers in our body's connective tissues, such as skin, ligaments, and blood vessel walls. These fibers create a supportive framework that provides elasticity and strength, helping tissues to stretch and return to shape. Fibrillin also plays a crucial role in the formation of microfibrils that support the growth and development of elastic fibers. Proper functioning of fibrillin is vital for maintaining the integrity and flexibility of tissues, and defects can lead to connective tissue disorders like Marfan syndrome, affecting the heart, eyes, and skeleton.
