Research Abstract

We have identified SPSB family of proteins as an iNOS-binding protein. SPSB family of proteins function as an adaptor protein that bridges between iNOS and the Elongin B/C-Cul5-type E3 ubiquitin ligase, and induce the ubiquitin/proteasome-dependent degradation of iNOS. SPSB family of proteins play an essential role in protection against the cytotoxic effect of iNOS.
