Based on limited published evidence, GATD1 is a component of the FERRY (Five-subunit Endosomal Rab5 and RNA/ribosome intermediary) complex 12. The complex functions as a RAB5A effector that directly interacts with mRNAs and mediates their endosomal transport and localization 1. GATD1 contributes to recruiting mRNAs and ribosomes to early endosomes, likely facilitating localized translation in cells with extensive cellular processes 3. While other FERRY complex members are associated with neurogenetic disorders, no mutations in GATD1 have yet been linked to disease 3.
