SI0604P: K6-Linked Tetra-Ubiquitin (Phosphorylated)

K6-linked ubiquitination is traditionally associated with mitophagy and also a main contributor to the DNA damage response.  These chain types are also involved in protein stabilization and other non-degradative processes. Phospho-ubiquitin chains represent a specialized class of polyubiquitin characterized by phosphorylation at Serine 65 and play a central role in mitophagy signaling pathways. K6 Tetra-Ubiquitin (phosphorylated) is a tetrameric chain of wild-type ubiquitin, wherein ubiquitin monomers are enzymatically linked together via an isopeptide bond between Lysine 6 and the C-terminal Glycine. The chains are then enzymatically phosphorylated at the Ser65 position.
