Ubiquitin-dependent degradation

Ubiquitin-dependent degradation is a natural process where the cell identifies and breaks down unnecessary or damaged proteins. This involves tagging these proteins with a small protein called ubiquitin, like a molecular "waste label." Once labeled, the tagged proteins are directed to a structure called the proteasome, which acts like a recycling center, dismantling the proteins into basic building blocks. This process helps maintain cellular health, regulate protein levels, and prevent the accumulation of potentially harmful proteins. It’s an essential system for cell maintenance, quality control, and proper functioning.
