Mitochondrial volume fraction and translation duration impact mitochondrial mRNA localization and protein synthesis.

abstract：:Genomic sequencing has implicated large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system is needed to validate gene associations with pathology. We developed a Drosophila-based functional system to screen candidate disease genes identified from Congenital...
