NEET proteins belong to a unique class of [2Fe-2S] cluster proteins that have been shown to participate in various biological processes such as regulating iron, reactive oxygen species and apoptosis within the cell and are localized to the mitochondria. Disruption of the mitochondrial NEET proteins are associated with different human diseases such as obesity, neurodegeneration, cancer and diabetes. In humans, a missense mutation in the CISD2 gene results in a heritable multisystem disorder termed Wolfram syndrome 2 (WFS2), a disease which displays an early onset of juvenile diabetes and various neuropsychiatric disorders. The C. elegans genome contains three previously uncharacterized cisd genes: cisd-1, which has homology to the human CISD1 and CISD2, and cisd-3.1 and cisd-3.2, both of which have homology to the human CISD3. Disruption of the cisd-3 gene(s) function results in mis-regulation of proteostasis in the mitochondria, whereas cisd-1 and cisd-3.1 disruption impacts proteostasis in the endoplasmic reticulum. Reduction of cisd-3.2 gene function also leads to a developmental delay in C. elegans. A knockout mutation of the cisd-3.2(pn68) gene function results in various germline defects including delayed development progression and morphological defects. Furthermore, I show the cisd gene(s) and protein expression profiles is present relative to sex, tissue …
