Activity-regulated cytoskeleton-associated protein (Arc), also known as Arg3.1, is a protein that plays a crucial role in synaptic plasticity and memory formation. It is primarily expressed in neurons and is regulated by neuronal activity, which means its expression can be increased following synaptic stimulation.
