Regulated compartmentalization of the putative DEAD-box helicase MDDX28 within the mitochondria in COS-1 cells.

Abstract excerpt

We recently cloned a putative DEAD-box helicase MDDX28 and found that it was localized to the nuclei and mitochondria of COS-1 cells. The mitochondrial localization of MDDX28 is largely diffuse. We have, however, used immunofluorescence and immunogold cytochemistry to show that the MDDX28 protein is localized in a distinct mitochondrial subcompartment in 5-10% of COS-1 cells. This proportion increases to...
