ubiquitination
Ubiquitination is a process where a small protein called ubiquitin attaches to other proteins in our cells. This tagging signals that the marked proteins should be degraded or recycled. Think of it as putting a "recycle" sticker on a used item. Ubiquitination helps regulate various cellular processes, including protein lifespan, cell division, and responses to stress. By managing these proteins, ubiquitination plays a critical role in maintaining overall cellular health and function, and it has implications in various diseases, including cancer and neurodegenerative disorders.

Ubiquitination is a biological process where a small protein called ubiquitin attaches to another protein, marking it for degradation or altering its function. This "tagging" signals to the cell's machinery that the tagged protein needs to be broken down or recycled. It's a crucial regulatory mechanism that helps maintain the balance of proteins in cells, affecting various cellular processes like cell division, DNA repair, and responses to stress. Essentially, ubiquitination helps control which proteins are active, contributing to overall cellular health and function.
