Parkin- An E3 Ubiquitin Ligase with Multiple Substrates

Anna Sandebring and Angel Cedazo-Minguez

Parkinson’s disease is a common neurodegenerative disorder. The clinical symptoms arise from a substantial loss of dopaminergic neurons in substantia nigra pars compacta, which causes motor symptoms such as bradykinesia and tremor. Although the majority of PD cases are sporadic, there is a growing number of genes shown to be involved in causing parkinsonism that manifests with similar pathology to the idiopathic disease. The most common cause to autosomal recessive parkinson’s disease (ARPD) is mutations in the gene encoding for parkin- an E3 ubiquitin ligase with widespread functions in the cell. In this review we summarize the substrates identified for parkin and which functions these imply in the cell. Elucidating the mechanism of functions of these substrates may contribute with clues on which pathways to study further in Parkinson’s disease pathology.
