Research Description

Seunghyi was a post-doc in the lab until 2014. She worked on several projects, all of which are collaborative with the lab of Eugenia Gurevich. Seunghyi focused on the role of arrestins in the activation of JNK family kinases, that often stop cell proliferation and induce cell death, as well as on direct functions of non-visual arrestins in apoptotic cell death. She recently discovered that caspase-cleaved arrestin-2 translocates to mitochondria and facilitates cytochrome C release induced by another product of caspase activity, tBid, but not other Bcl family members. This was the first demonstration that arrestins play direct role in the core of cell death machinery.

In collaboration with Eugenia we have recently discovered that arrestins bind ubiquitin ligase parkin, mutations in which are implicated in familial Parkinson’s disease. We discovered that parkin binding promotes arrestin interaction with another E3 ubiquitin ligase, Mdm2. Seunghyi is elucidating the mechanism of arrestin interactions with these two ubiquitin ligases and its role in the regulation of parkin activity in cells.

Seunghyi published fifteen papers and chapters from the lab:
