The Molecular Bond That Helps Secure Your Memories

SMRTR summary

Scientists discovered a persistent bond between two proteins, PKMζ and KIBRA, that helps maintain long-term memories in the brain. This interaction allows memories to last despite molecular turnover, addressing a long-standing question in neuroscience. The findings suggest these protein complexes are crucial for forming and preserving memories over time by maintaining strengthened synaptic connections between neurons.
