Invitro models for understanding role of pSer65UB in pathogenesis of PD.
Mitophagy (the autophagic processing of damaged mitochondria) via Parkin activation is mainly promoted by K6 and K63 linked chains. K6-linked ubiquitination is also a main contributor to the DNA damage response and acts as a DNA-binding enhancer during the innate immune system response. These chain types are also involved in protein stabilization and other non-degradative processes.
These di-ubiquitin chains are generated from the enzymatic linkage of wild-type ubiquitin through lysine 6. The K6 di-ubiquitin is then phosphorylated via enzymatic reaction with Tribolium castaneum PINK1 kinase (PTEN-induced kinase 1) at Ser 65.
