CC   -!- FUNCTION: Part of a cell division machinery.
CC       {ECO:0000269|PubMed:24399085}.
CC   -!- INDUCTION: Expression is highest in dividing cells.
CC       {ECO:0000269|PubMed:19008417}.
CC   -!- DISRUPTION PHENOTYPE: Deletion mutant forms small colonies on selective
CC       plates. Forms enlarged cells, with a highly elevated content of DNA.
