Mutations in the parkin gene are a common cause of autosomal recessive early-onset parkinsonism. Parkin functions as an E3 ubiquitin ligase where it can polyubiquitinate a number of its protein substrates, thus targeting them for degradation by the 26 S proteasomal complex. Recent studies have demonstrated that alternative modes of parkin-mediated ubiquitination may serve other non-degradative regulatory roles. In addition, parkin appears to function as a multipurpose neuroprotectant in a number of toxic paradigms. Coupled with these observations, parkin may integrate other gene products associated with parkinsonism, including α-synuclein, LRRK2 (leucine-rich repeat kinase 2), DJ-1 and PINK1 [PTEN (phosphatase and tensin homologue deleted on chromosome 10)-induced putative kinase 1], into a common biochemical pathway of potential relevance to disease pathogenesis. Parkin therefore represents a unique multifaceted ubiquitin ligase consistent with an important housekeeping role in maintaining the integrity or survival of dopaminergic neurons.

CONSTITUTIVE PHOTOMORPHOGENIC 1 functions as an E3 ubiquitin ligase in plants and animals. Discovered originally in Arabidopsis thaliana, COP1 acts in a complex with SPA proteins as a central repressor of light-mediated responses in plants. By ubiquitinating and promoting the degradation of several substrates, COP1/SPA regulates many aspects of plant growth, development and metabolism. In contrast to plants, human COP1 acts as a crucial regulator of tumorigenesis. In this review, we discuss the recent important findings in COP1/SPA research including a brief comparison between COP1 activity in plants and humans.
