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 key role in vesicle transport and overall cellular logistics. Dysregulation of RABGAP1L may disrupt cellular transport mechanisms and has been studied in relation to neurological disorders, where proper membrane trafficking is essential for neuronal function.
