Research Abstract

The optineurin (OPTN) E50K mutation was first identified in familial glaucoma. We have previously described an E50K mutation-carrying transgenic (E50K-tg) mouse that exhibited glaucomatous phenotypes. Further phenotypic analysis of these E50K-tg mice revealed the abnormal localization of E50K mutant protein deposits in retina, indicating a mutant protein aggregation/insolubility. Neurons derived from induced pluri potent stem cells (iPSCs) from E50K-glaucoma patients exhibited increased insolubilized OPTN. The E50K mutant strongly interacted with TBK1 and treatment with a TBK1 inhibitor abrogated the aberrant insolubility of E50K. Here, we delineated the underlying pathoetiology of E50K-glaucoma associating with mutant protein aggregation.
