SYNPOSynaptopodin is a protein that in humans is encoded by the SYNPO gene.FunctionSynaptopodin is an actin-associated protein that may play a role in actin-based cell shape and motility. The name synaptopodin derives from the protein's associations with postsynaptic densities and dendritic spines and with renal podocytes.InteractionsSYNPO has been shown to interact with MAGI1.
