**Background of ARC Recombinant Protein**
ARC (Activity-regulated cytoskeleton-associated protein), also known as Arg3.1. is a plasticity-related protein predominantly expressed in neurons. Discovered in the 1990s, ARC plays a critical role in synaptic plasticity, learning, and memory consolidation. It is tightly regulated by neuronal activity and is essential for long-term potentiation (LTP) and long-term depression (LTD), processes underlying synaptic strengthening and pruning. ARC interacts with cytoskeletal components and signaling molecules, modulating dendritic spine morphology and receptor trafficking, particularly for AMPA-type glutamate receptors. Dysregulation of ARC is implicated in neurological disorders, including Alzheimer’s disease, schizophrenia, and fragile X syndrome.
Recombinant ARC protein is produced using genetic engineering techniques, enabling large-scale, standardized study of its structure and function. By cloning the ARC gene into expression vectors (e.g., bacterial, mammalian, or insect cell systems), researchers generate purified ARC with minimal batch variability. This approach circumvents challenges in isolating native ARC from brain tissue, which is low in abundance and difficult to purify.
Recombinant ARC has advanced studies on its role in synaptic scaling, RNA trafficking, and viral-like capsid formation—a unique feature allowing ARC to transfer RNA between cells. It also aids in structural analyses (e.g., X-ray crystallography, cryo-EM) to map functional domains and interactions. Therapeutic applications are being explored, such as targeting ARC pathways to treat memory disorders or leveraging its RNA delivery mechanism for gene therapy.
Overall, recombinant ARC protein serves as a vital tool for deciphering neural plasticity mechanisms and developing neurotherapeutics.
