CC   -!- FUNCTION: Involved in cell division and chromosome segregation
CC       (PubMed:24065632). Plays a central role in the initiation of
CC       sporulation through the activation of multiple components of the cell
CC       division machinery (PubMed:24065632). Acts as a transcriptional
CC       regulator that is involved in the direct control of genes required for
CC       key steps in sporulation, including the cessation of aerial growth, the
CC       initiation of cell division, and chromosome segregation. Functions
CC       almost equally as an activator and as a repressor (PubMed:24065632).
CC       Required for DNA binding by WhiB. May function cooperatively with WhiB
CC       (PubMed:27094333). {ECO:0000269|PubMed:24065632,
CC       ECO:0000269|PubMed:27094333}.
CC   -!- ACTIVITY REGULATION: DNA binding depends on WhiB.
CC       {ECO:0000269|PubMed:27094333}.
CC   -!- INDUCTION: Autoregulated. Expressed throughout vegetative growth and
CC       sporulation. Could be post-translationally regulated.
CC       {ECO:0000269|PubMed:24065632}.
CC   -!- DISRUPTION PHENOTYPE: Mutants form unusually long aerial hyphae that
CC       fail to initiate septation or chromosome segregation.
CC       {ECO:0000269|PubMed:24065632}.
CC   -!- SIMILARITY: Belongs to the WhiA family. {ECO:0000255|HAMAP-
CC       Rule:MF_01420}.
