In this study, the authors report that target-derived NGF signaling induces the expression of Coronin-1, which consequently gets recruited to the NGF-TrkA–carrying signaling endosome, where it regulates endosomal fusion with lysosomes, trafficking and recycling. In addition, Coronin-1 appears to be necessary for NGF-dependent signaling events such as CREB phosphorylation, Ca2+ release and activation of calcineurin.
