UBE1

UBE1, also known as ubiquitin-activating enzyme 1, is a crucial protein involved in the process of removing and recycling damaged or unneeded proteins in cells. It acts like a “starter” that kicks off the ubiquitination process by activating a small protein called ubiquitin. Once activated, ubiquitin attaches to target proteins, marking them for destruction or other cellular activities. This process helps maintain healthy cell function, prevents accumulation of faulty proteins, and is vital for cell regulation, growth, and response to stress.
