Neuronal mitochondria transport Pink1 mRNA via synaptojanin 2 to support local mitophagy
Actions 
Order Assays
PTEN-induced kinase 1 (PINK1) is a short-lived protein required for the removal of damaged mitochondria through Parkin translocation and mitophagy. Because the short half-life of PINK1 limits its ability to be trafficked into neurites, local translation is required for this mitophagy pathway to be active far from the soma. The Pink1 transcript is associated and cotransported with neuronal mitochondria. In concert with translation, the mitochondrial outer membrane proteins synaptojanin 2 binding protein (SYNJ2BP) and synaptojanin 2 (SYNJ2) are required for tethering Pink1 mRNA to mitochondria via an RNA-binding domain in SYNJ2. This neuron-specific adaptation for the local translation of PINK1 provides distal mitochondria with a continuous supply of PINK1 for the activation of mitophagy.

Neurological diseases are on the rise – and as societies age, they affect an ever-increasing number of people, not only in Europe, but worldwide.
The Munich Cluster for Systems Neurology (SyNergy) investigates how complex neurological diseases such as Alzheimer's disease, stroke, and multiple sclerosis develop. Even though these diseases differ in their clinical manifestations, overlapping mechanisms are involved in their development. For example, the immune system gets activated in dementia, ...

This project serves as a centralized repository for omics datasets published by research groups within the SyNergy Cluster. It encompasses investigations such as proteomics and transcriptomics, which are further divided into individual studies led by SyNergy members. Each study is linked to relevant publications, assays and data files (with links to external repositories).
