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.

Cottontails usually wean around 3-4 weeks, so you should not give formula past 6 weeks. Wild Jackrabbits wean after 9 weeks, so after 9 weeks slowly replace formula with a dish of cut up tiny bananas and apple pieces. At 2-3 weeks, also start introducing them to 'timothy hay', oat hay, pellets and water (add fresh greens for wild rabbits). 2  3-6 weeks: 13-15cc/ml each feeding twice per day (less if the rabbit is very small).
