DJ-1 inhibits PTEN, a negative regulator of PI3K/Akt signaling and also
binds to certain mRNA transcripts in a manner that inhibits their translation.
TORC1 activity may contribute to PINK1/Parkin pathology potentially through
mRNA translation. Mutations in the translation initiation factor eIF4G1 likely
cause PD. Additionally, LRRK2 stimulates mRNA translation through interaction
with the ribosome and phosphorylation of s15. Hence, tightly regulated
translation is crucial for cellular function and survival and loss of this
control may predispose to disease (1).
