**Background of RAB3IL Recombinant Protein**
RAB3IL (RAB3A-interacting protein-like), also known as guanine nucleotide exchange factor for RAB3A (GEF), is a cytosolic protein implicated in regulating synaptic vesicle trafficking and exocytosis. It belongs to the SEC2 family of proteins, which function as guanine nucleotide exchange factors (GEFs) for small GTPases in the RAB family. RAB3IL specifically activates RAB3A, a GTPase critical for neurotransmitter release in presynaptic neurons, by catalyzing the exchange of GDP for GTP, thereby modulating RAB3A’s activity in vesicle docking and fusion processes.
Structurally, RAB3IL contains conserved domains such as a coiled-coil region and a catalytic GEF domain. Recombinant RAB3IL protein is typically produced in expression systems like *E. coli* or mammalian cells, enabling studies of its biochemical interactions and functional mechanisms. Its recombinant form retains the ability to bind RAB3A and other partners, making it a valuable tool for *in vitro* assays, including GTPase activation studies, protein-protein interaction analyses, and structural investigations.
Research on RAB3IL has highlighted its role beyond neuronal signaling, suggesting involvement in endocrine secretion and intracellular transport pathways. Dysregulation of RAB3IL or RAB3A has been linked to neurodevelopmental disorders and secretory defects, underscoring its physiological importance. Recombinant RAB3IL facilitates exploration of these pathways, aiding drug discovery and mechanistic studies of diseases like Alzheimer’s and diabetes. Overall, RAB3IL recombinant protein serves as a key reagent for deciphering RAB-mediated trafficking and its implications in health and disease.
