The aim of this study was to elucidate the molecular pathogenesis of aceruloplasminemia by a functional analysis of mutant ceruloplasmin.MethodsThe effects of nonsense mutations including Y694ter, W858ter and R882ter were studied by the expression in cultured cells.ResultsA biogenesis study demonstrated that the Y694ter and W858ter mutants showed protein synthesis identical to that of wild type protein, however, the mutants were retained in the endoplasmic reticulum (ER), while R882ter mutant was secreted out. Site-directed mutagenesis analyses suggested that Cys-881 was necessary for the secretion of the truncated ceruloplasmin. The W858ter mutant decreased viability in the transfected cells. The expression and the promoter activity of glucose-regulated protein 78 that is an ER stress sensor protein, were up-regulated in the transfected cells.ConclusionsThe truncated mutant containing Cys-881 was able to pass through the ER and was secreted, while the truncated mutant protein without Cys-881 appeared to accumulate in the ER thus leading to ER stress and eventually resulting in cell death."xsd:string |
