SYNGAP1 is a critical neuronal protein encoded by the *SYNGAP1* gene, located on human chromosome 6. It functions as a Ras/Rap GTPase-activating protein (GAP), regulating synaptic plasticity and excitatory signaling in the brain by modulating AMPA receptor trafficking and dendritic spine maturation. SYNGAP1 plays a pivotal role in early neurodevelopment, particularly in forming and maintaining excitatory synapses. Heterozygous mutations or deletions in *SYNGAP1* are strongly linked to neurodevelopmental disorders, including intellectual disability, autism spectrum disorder (ASD), and epilepsy. Patients often exhibit delayed motor skills, language deficits, and sensory processing abnormalities.
Recombinant SYNGAP1 protein is engineered in vitro using expression systems like *E. coli* or mammalian cells to study its molecular mechanisms or explore therapeutic strategies. Purified recombinant proteins retain functional domains, including the N-terminal Pleckstrin Homology (PH) domain, C2 domain, and the central GAP domain, enabling researchers to analyze interactions with synaptic partners (e.g., PSD-95. NMDA/AMPA receptors) or assess how pathogenic variants disrupt synaptic function. These tools are vital for high-throughput drug screening, structural studies, or gene therapy development targeting *SYNGAP1*-related disorders. Recent advances in gene replacement or CRISPR-based editing further highlight the therapeutic potential of SYNGAP1 recombinant proteins in rescuing synaptic deficits in preclinical models. However, challenges remain, including optimizing protein stability, delivery methods, and ensuring isoform-specific effects, as SYNGAP1 has multiple splice variants with distinct roles. Ongoing research aims to translate these insights into targeted interventions for *SYNGAP1*-associated neurodevelopmental conditions.
