General description【一般描述】 | Ubiqutin (Ub) is initially produced as a 229-a.a. Polyubiquitin-B (UniProt P0CG47) precursor protein encoded by the UBB gene (Gene ID 7314) or a 685-a.a. Polyubiquitin-C precursor protein (UniProt P0CG48) encoded by the UBC gene (Gene ID 7316) in human. Posttranslational cleavages yield multiple copies of idential 76-amino acid ubiquitin (also known as high mobility group nonhistone protein HMG-20) molecules. Ub is involved in one of the most common post-translational modifications (PTMs) of cellular proteins, where Ub is linked covalently via its carboxyl terminus (Gly76) to usually Lys residues in target proteins. A given target Lys residue can be linked to one single Ub molecule (monoubiquitylated) or to a chain of Ub molecules (polyubiquitylated). In a polyUb chain, Ub molecules can be linked through one of the seven Lys residues (K6, K11, K27, K29, K33, K48, and K63) or through the Ub N-terminus Met1 residue (which generates linear chains). Lys-C is an endopeptidase that cleaves proteins on the C-terminal side of unmodified lysine residues, but not Ub-modified Lysine residues, generating peptide fragments with a C-terminus Lysine and internal Lysine residue(s) linked to a Ub C-terminal remnant (as a result of Lys-C cleavage between Ub K63 and E64). Antiboides that specifically target this Ub C-terminal remnant (i.e. E64 to Gly76 or E48 to Gly76 if K63 is ubiquitinated in a polyUb chain) are compatible with the patented UbiSite |
Specificity【特异性】 | Clone 2G7B8 detects monoubiquitinated (MonoUb) and polyubiquitinated (polyUb) proteins, as well as free ubiquitin (Ub) molecule by targeting Ub sequence C-terminal to Lys63 (UbiSite Broad species reactivity expected based on 100% sequence homology. |
