Synaptotagmin-3 (SYT3) is a calcium-binding protein belonging to the synaptotagmin family, which plays critical roles in regulating synaptic vesicle exocytosis and membrane trafficking in neuronal and non-neuronal cells. As an integral component of synaptic transmission, SYT3 is distinguished by its unique calcium-sensing properties and subcellular localization. Unlike its closely related isoform SYT1. which is a primary calcium sensor for fast neurotransmitter release, SYT3 exhibits slower calcium dissociation kinetics and is enriched in postsynaptic compartments or specific secretory pathways, suggesting divergent functional roles in modulating synaptic plasticity, endocytosis, or intracellular signaling.
Recombinant SYT3 protein is engineered to enable detailed biochemical and structural studies. It is typically produced using heterologous expression systems, such as Escherichia coli or mammalian cell cultures, followed by purification via affinity chromatography. The recombinant protein retains key functional domains, including two calcium-binding C2 domains (C2A and C2B) that mediate interactions with phospholipids, SNARE proteins, and other synaptic machinery. Researchers utilize SYT3 recombinant proteins to investigate calcium-dependent membrane fusion mechanisms, screen for interacting partners, or study mutations linked to neurological disorders.
Emerging evidence implicates SYT3 in neurodevelopmental and neurodegenerative conditions, such as Alzheimer’s disease, highlighting its potential as a therapeutic target. Its recombinant form serves as a vital tool for deciphering synaptic dysregulation and developing targeted interventions. Ongoing research aims to clarify its tissue-specific functions and regulatory pathways, bridging gaps in understanding synaptic diversity and adaptive neuronal communication.
