First work of 2020 work is out for the NeuroCyto team! A collaboration with Matt Rasband’s lab in Nature Communications. This is a significant paper for the axon initial segment field: Matt’s lab used BioID of key AIS proteins for mapping AIS components. Dozens of new candidates for future studies! We performed super-resolution microscopy of several of the newly identified AIS components. IN particular, we showed that Mical3, a protein linking microtubules and actin, forms clusters along the AIS that are not periodically organized along the actin/spectrin scaffold.
