Septin-1 is a protein that in humans is encoded by the SEPT1 gene.[5][6]


This gene is a member of the septin family of GTPases. Members of this family are required for cytokinesis. This gene encodes a protein associated with the tau-based paired helical filament core, and may contribute to the formation of neurofibrillary tangles in Alzheimer's disease.[6]
