**Background of Recombinant Human CPLX3 Protein**
Recombinant human CPLX3 (Complexin-3) is a synthetically produced protein crucial for studying synaptic transmission and neurochemical regulation. CPLX3 belongs to the complexin family, which modulates synaptic vesicle exocytosis by interacting with the SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) complex. It acts as a dual-function regulator, stabilizing primed vesicles to prevent spontaneous release while enhancing synchronous neurotransmitter release upon calcium influx.
CPLX3 is predominantly expressed in specific neuronal subtypes, including inhibitory interneurons, suggesting its role in fine-tuning neural circuit dynamics. Dysregulation of complexins has been linked to neurological disorders such as epilepsy, schizophrenia, and neurodegenerative diseases, making CPLX3 a target for mechanistic and therapeutic research.
Recombinant CPLX3 is generated via heterologous expression systems (e.g., *E. coli* or mammalian cells*), enabling high-purity yields for *in vitro* studies. Its applications span structural analyses (e.g., X-ray crystallography), functional assays (e.g., vesicle fusion reconstitution), and drug screening. By providing a controlled source of the protein, recombinant CPLX3 facilitates exploration of synaptic regulation mechanisms and potential interventions for synaptic dysfunction.
This engineered tool bridges molecular neuroscience and translational research, offering insights into both basic synaptic biology and disease pathology. (Word count: 200)
