Descrizione

Descrizione generale

Research Area: CANCER
Ubiquitin is a highly conserved protein composed of 76 amino acids, and it is expressed universally in all eukaryotes, ranging from yeast to humans.

Ubiquitin, a globular protein is made of 76 amino acids and has lysine residues on its surface. It has a molecular weight of 8565 Da.N-Terminal histidine-tagged ubiquitin can replace native ubiquitin in the formation of poly-ubiquitin—protein conjugates. The histidine tag enables the separation and enrichment of protein conjugates on a Ni(II) column and the detection of conjugates in western blot by anti-histidine-tag antibodies.

Applicazioni

Ubiquitin human can be used as a test compound for studying the isolation and characterization of rice E3-ubiquitin ligase and the role of OsHOS1 gene in the modulation of the cold stress response.

Ubiquitin human has been used:

• as a substrate in in vitro ubiquitination assays
• as substrate in ADP-ribosylation and ubiquitylation assays
• to supplement the 64 ng of endogenous ubiquitin in fresh blood for experiment grouping in order to study its potential clinical impact on cancer prognosis

Azioni biochim/fisiol

Ubiquitin is a small regulatory protein present in eukaryote tissues. Exogenous ubiquitin can stimulate apoptosis in numerous cell lines. E7 protein of human papilloma virus-16 stimulates Retinoblastoma Protein degradation via Ubiquitin-Proteasome Pathway.

Ubiquitin plays a key role in normal eukaryotic cell function. It participates in the development and function of the immune system. This immunophilin is also known to participate in immune homeostasis. The ubiquitin peptide fragment (U50-59) is capable of blocking cellular and humoral immunity.

Ubiquitin-mediated proteolysis plays an important role in several basic cellular processes including regulation of cell cycle and division, differentiation and development, modulation of cell-surface receptors, the secretory pathway (protein transport), morphogenesis of neuronal networks, transcriptional regulation and signal transduction, transcriptional silencing, DNA repair, long-term memory, and circadian rhythms.

Nota sulla preparazione

Ubiquitin human can dissolved in 0.02 M Tris-HCl at a concentration of 1.00 - 1.10 mg/ml to yield a clear to slightly hazy, colorless solution.
