STON1 (Stonin 1) is an endocytic adaptor protein primarily involved in clathrin-mediated endocytosis (CME), a critical process for membrane trafficking and cellular signaling. It belongs to the evolutionarily conserved stoned protein family, sharing structural homology with the μ-homology domain (μHD) of adaptor protein complex 2 (AP2), which enables cargo recognition. STON1 is enriched in neuronal tissues, where it regulates synaptic vesicle recycling by facilitating the sorting and internalization of specific transmembrane receptors, including synaptic vesicle proteins like synaptotagmin-1. This function ensures efficient neurotransmission and maintenance of synaptic plasticity. Unlike its homolog STON2. STON1 exhibits preferential binding to certain cargoes through its C-terminal domain, acting as a cargo-specific adaptor. Studies link STON1 dysregulation to neurological and psychiatric disorders, such as schizophrenia and autism spectrum disorders, likely due to impaired synaptic function. Recombinant human STON1 protein is widely used in biochemical assays, structural studies, and drug discovery to elucidate its interaction networks and role in disease mechanisms. Its modular architecture and role in orchestrating vesicle trafficking make it a key molecular tool for exploring CME pathways and developing targeted therapies for synaptic disorders.
