Rutgers University–New Brunswick researchers have identified how the brain protein cypin helps strengthen neural connections, offering hope for new treatments for Alzheimer’s, Parkinson’s, and brain injuries. The breakthrough study, published in Science Advances, reveals cypin’s critical role in synaptic stability, the process that underpins learning and memory.

How Cypin Supports Brain Function

Cypin maintains the stability of synapses — the tiny junctions where neurons communicate — by increasing the tagging of certain proteins. These molecular tags guide proteins to their correct positions in the brain, ensuring smooth neuron signaling. Correct placement is vital for healthy brain communication and cognitive function.

Proteasome Interaction Slows Protein Breakdown

The Rutgers team found that cypin interacts with the proteasome, a protein complex that removes damaged or unnecessary proteins. When bound to the proteasome, cypin slows protein degradation, allowing beneficial proteins to accumulate at synapses. This buildup strengthens communication between neurons, directly enhancing learning and memory retention.

Dual Action: Cypin and UBE4A Activation

Cypin also boosts the activity of UBE4A, a protein that plays a role in the tagging process. This dual action — slowing degradation and improving tagging — makes cypin a powerful regulator of synaptic health. Increased cypin levels result in stronger neural connections and better brain adaptability, or synaptic plasticity.

Implications for Neurodegenerative Diseases

Lead researcher Professor Bonnie Firestein notes that therapies targeting cypin could restore healthy brain function in conditions where neuron communication is damaged. This includes neurodegenerative disorders like Alzheimer’s and Parkinson’s, as well as recovery from traumatic brain injuries.

Although this research is still in its early stages, its potential for real-world applications is significant. By protecting and enhancing synaptic health, cypin could become a cornerstone of future neuroprotective treatments.
