P62 (sequestosome 1)

P62, also known as sequestosome 1, is a protein that plays a crucial role in cellular clean-up processes. It helps identify and direct damaged or unnecessary proteins and cellular components to structures called autophagosomes, where they are broken down and recycled. This function is vital for maintaining healthy cell function and preventing the buildup of harmful materials, which can contribute to diseases like cancer, neurodegeneration, and inflammation. In essence, P62 acts like a cellular waste manager, helping cells stay clean and functioning properly.
