AP180 is a protein involved in endocytosis and thus in signal transmission between nerve cells. This protein, which largely lacks a three-dimensional structure, has never been fully studied. Using solution NMR spectroscopy, scientists from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) were now able to examine each of its 600 unstructured amino acids individually and discovered a new interaction network. The work has model character. The paper was recently published in „Nature Communications.“
