Description
General description
Polyubiquitin chains linked through the Lys48 residue of ubiquitin are most commonly associated with proteins targeted for proteosomal degradation. In contrast, polyubiquitin chains linked through the Lys63 residue of ubiquitin (Ub) are associated with nonproteolytic functions such as signal transduction. Lys63-linked polyUb chains connect components of NFκB signaling in a highly regulated manner, and genetic evidence indicates the involvement of Lys63-linked Ub chains in stress response and DNA repair. Research in yeast has suggested Lys63-linked Ub chains stimulate endocytosis.
varies
Immunogen
Epitope: Lys63 ubiquitination site
Immunogen used was a branched peptide corresponding to the Lys63 ubiquitination site. The C-terminus of Ubiquitin 71-76 peptide (RLRGG) was attached to the K63 in the Ubiquitin 58-63 peptide (CDYNIQKEST).
Application
Anti-Ubiquitin Antibody, Lys63-Specific, clone HWA4C4 is an antibody against Ubiquitin for use in ELISA, IH, IC & WB.
