Overview
SEPT3 belongs to the septin family of GTPases. Members of this family are required for cytokinesis. Expression is upregulated by retinoic acid in a human teratocarcinoma cell line. The specific function of this gene has not been determined. This gene encodes three transcript variants resulting in three distinct isoforms. Note: This description may include information from UniProtKB.
