CC -!- FUNCTION: Plays a role in the cell cycle. Involved in a late stage of
CC septum formation leading to the separation of the daughter cells.
CC {ECO:0000269|PubMed:15385632}.
CC -!- SUBUNIT: Component of the septin complex composed of two copies of each
CC spn1, spn2, spn3 and spn4. {ECO:0000269|PubMed:15385632}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cell cortex
CC {ECO:0000269|PubMed:15385632}. Note=Localizes to the medial ring at the
CC cell cortex of dividing cells.
CC -!- SIMILARITY: Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like
CC GTPase superfamily. Septin GTPase family. {ECO:0000255|PROSITE-
CC ProRule:PRU01056}.
