This research provides a comprehensive proteomic and functional analysis of the membrane-associated periodic skeleton (MPS), a lattice structure in neurons made of actin and spectrin. By utilizing mass spectrometry, the scientists identified hundreds of candidate proteins that interact with this skeleton, spanning categories like motor proteins, ion channels, and signaling molecules. Through super-resolution imaging (STORM), they confirmed that approximately 20 of these proteins exhibit the periodic distribution characteristic of the MPS. The study further demonstrates that non-muscle myosin…
