**Background of NXPH3 Recombinant Protein**
Neurexophilin-3 (NXPH3) is a secreted glycoprotein belonging to the neurexophilin family, which interacts with neurexin transmembrane proteins to regulate synaptic connectivity and intercellular signaling in the nervous system. Encoded by the *NXPH3* gene in humans, it is selectively expressed in GABAergic neurons and plays a role in modulating inhibitory neurotransmission. Structurally, NXPH3 contains a conserved N-terminal domain for binding to α-neurexins and a C-terminal region implicated in extracellular matrix interactions, facilitating its role in synaptic adhesion and stabilization.
Recombinant NXPH3 protein is engineered using heterologous expression systems (e.g., mammalian or insect cells) to ensure proper post-translational modifications, such as glycosylation, critical for its functional activity. This protein is purified via affinity tags (e.g., His-tag) and validated through assays like Western blot or ELISA. Its applications span *in vitro* studies exploring neurexin-mediated signaling, synaptic plasticity mechanisms, and GABAergic pathway dysregulation linked to neurodevelopmental disorders.
Research highlights NXPH3's interaction with LRRTM4 (leucine-rich repeat transmembrane protein 4), suggesting its involvement in organizing inhibitory synapses. Dysregulation of NXPH3 has been tentatively associated with autism spectrum disorders and schizophrenia, making it a potential biomarker or therapeutic target. The recombinant form enables precise mechanistic studies, aiding drug discovery and advancing neurobiology research.
In summary, NXPH3 recombinant protein serves as a vital tool for dissecting synaptic biology and neuropathologies, bridging structural biochemistry with functional neuroscience.
