Study Examines Proteins’ Roles in Mitochondrial Recycling

PINK1 and Parkin — two proteins whose deficiency has been linked to early-onset Parkinson’s — are involved in the degradation and recycling of mitochondria in neurons, a study shows. While these proteins were known to contribute to mitochondrial recycling in other cell types, this study provides a closer look into mitochondria’s life cycle in neurons, confirming not only PINK1 and Parkin’s role, but also uncovering a new recycling pathway. “This work gives us unprecedented insight into mitochondria’s…
