The Synapsin (phospho-Ser549) antibody is a specialized tool used to study the phosphorylation state of Synapsin proteins at serine residue 549. a post-translational modification critical for regulating synaptic function. Synapsins are a family of neuron-specific phosphoproteins (Synapsin I, II, III) that play pivotal roles in modulating synaptic vesicle dynamics, neurotransmitter release, and synaptogenesis. They act as molecular scaffolds, tethering synaptic vesicles to the actin cytoskeleton in presynaptic terminals, thereby controlling vesicle mobilization and availability for exocytosis. Phosphorylation at specific residues, including Ser549. alters Synapsin’s interactions with vesicles or cytoskeletal elements, influencing synaptic plasticity and signal transmission.
The phosphorylation of Synapsin at Ser549 is associated with signaling pathways activated during neuronal activity, often mediated by kinases such as PKA, CaMKII, or MAPK. This modification is thought to reduce Synapsin’s binding affinity for vesicles, promoting their release from the reserve pool to the active zone during high-frequency stimulation. The Synapsin (phospho-Ser549) antibody enables researchers to detect and quantify this phosphorylation event, providing insights into activity-dependent synaptic changes in physiological or pathological contexts, such as learning/memory studies, neurodegenerative diseases (e.g., Alzheimer’s), or psychiatric disorders.
Validated for applications like Western blotting, immunohistochemistry, and immunofluorescence, this antibody’s specificity for the phosphorylated Ser549 epitope ensures accurate monitoring of Synapsin’s regulatory state. Its use has advanced understanding of how synaptic vesicle trafficking and neurotransmitter release are dynamically tuned by phosphorylation, bridging molecular mechanisms to broader neural network behaviors.
