RABGAP1L (RAB GTPase Activating Protein 1-Like): RABGAP1L is a gene that encodes a protein involved in intracellular membrane trafficking by regulating RAB GTPases. It plays a vital role in vesicle transport and overall cellular logistics. Dysregulation of RABGAP1L can disrupt cellular transport mechanisms and has been studied in connection with neurological disorders, where proper membrane trafficking is crucial for neuronal function.
