Ubiquitin-proteasome pathway

The ubiquitin-proteasome pathway is a cellular process that helps break down and recycle damaged or unneeded proteins. Cells attach a small protein called ubiquitin to these target proteins, marking them for disposal. These marked proteins are then recognized and broken down by a complex structure called the proteasome, which acts like a molecular garbage disposal. This system maintains cellular health by removing harmful proteins, regulating protein levels, and preventing build-up that could lead to diseases. Overall, it’s a vital mechanism for protein management and cell functioning.
