Descrição geral
Ubiquitin is a highly conserved globular protein and has lysine in the surface. The C-terminal end comprises the Leu-Arg-Gly-Gly structural motif.
Aplicação
Ubiquitin human can be used as a standard for mass spectrometry.
Ubiquitin human has been used in mono-ubiquitination of yeast proliferating cell nuclear antigen (PCNA) and in in vitro ubiquitination assay of defective in mitotic arrest 1 (Dma1)
Ubiquitin, N-terminal FLAG-tagged can replace the ubiquitin in formation of poly-ubiquitin—protein conjugates. The FLAG tag enables separation and enrichment of the protein conjugates on anti-FLAG affinity columns and detection of conjugates in western blot by anti-FLAG antibodies.
Ações bioquímicas/fisiológicas
Ubiquitin interacts with the lysine residue of proteins through its ε-amino group of the C-terminal glycine residue. Proteins interacting with ubiquitin either undergo mono-ubiquitination or multi-mono-ubiquitination via a three-step process. Ubiquitination regulates intracellular trafficking and protein degradation and an imbalance in the pathway is implicated in disorders.
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.

Protein ubiquitination and protein phosphorylation are two fundamental regulatory post-translational modifications controlling intracellular signalling events. However, the ubiquitin system is vastly more complex compared with phosphorylation. This is due to the ability of ubiquitin to form polymers, i.e. ubiquitin chains

Ubiquitin is a small globular protein that has a considerable number of lysine residues on its surface. This results in a high surface entropy that precludes the formation of crystal-packing interactions. To date, only a few structures of the native

Top-down proteomics, the analysis of intact proteins (instead of first digesting them to peptides), has the potential to become a powerful tool for mass spectrometric protein characterization. Requirements for extremely high mass resolution, accuracy, and ability to efficiently fragment large

Defective mobilization of Ca2+ by cardiomyocytes can lead to cardiac insufficiency, but the causative mechanisms leading to congestive heart failure (HF) remain unclear. In the present study we performed exhaustive global proteomics surveys of cardiac ventricle isolated from a mouse

The FLAG epitope is an eight amino acid peptide (AspTyrLysAspAspAspAspLys) that is useful for immunoaffinity purification of fusion proteins. A monoclonal antibody (anti-FLAG M1) that binds the FLAG epitope in a calcium-dependent manner and requires an N-terminal FLAG sequence has
