Ubiquitin: A small but extremely important protein that acts the kiss of death to other proteins. Ubiquitin consists of only 76 amino acids.In the normal course of events, proteins are inactivated by the attachment of ubiquitin to them, a process called ubiquitination. Ubiquitin acts as a tag by which the protein-transport machinery ferries a protein to the proteasome for degradation.Antagonizing this process are enzymes that remove ubiquitin from proteins. Ubiquitin is appropriately named since it is ubiquitous and is present in virtually all types of cells.biquitin acts as a tag by which the protein-transport machinery ferries a protein to the proteasome for degradation.

Answer by Alex Hughes-Walton. Confidence votes 6. We have a Welshie/Jack Russell mix who is 15 and going strong, despite spending the first seven years of her life churning out pups in a notorious puppy mill. Aside from a few stray white hairs, she can still pass for half her age.She runs like a gazelle, dances, etc.nswer by Alex Hughes-Walton. Confidence votes 6.

Jack Jones is 77 years old. To be more precise (and nerdy), the current age as of right now is 28123 days or (even more geeky) 674952 hours. That's a lot of hours!
