CC -!- FUNCTION: Involved in sporulation-specific cell division
CC (PubMed:19567872). Required for early stages of sporulation. Important
CC in the process of growth cessation prior to sporulation-specific cell
CC division. Recruits cell division protein FtsZ to the future septum
CC sites and tethers the contractile ring structure (Z ring) to the
CC cytoplasmic membrane during sporulation. Stimulates polymerization and
CC filament length of FtsZ in vitro (By similarity).
CC {ECO:0000250|UniProtKB:Q47N25, ECO:0000250|UniProtKB:Q9L268,
CC ECO:0000269|PubMed:19567872}.
CC -!- SUBUNIT: Interacts with SsgA. Interacts with FtsZ (via N-terminus).
CC {ECO:0000250|UniProtKB:Q47N25, ECO:0000250|UniProtKB:Q9L268}.
CC -!- SUBCELLULAR LOCATION: Cell septum {ECO:0000250|UniProtKB:Q9L268}.
CC Note=Localizes to the divisome in sporogenic aerial hyphae in a ladder-
CC like manner. Temporospatial localization is controlled by SsgA and it
CC colocalizes with SsgA in presporulation foci. Localizes to the septum
CC sites prior to FtsZ and after that colocalizes with FtsZ at the
CC divisome throughout cell division. {ECO:0000250|UniProtKB:Q9L268}.
CC -!- SIMILARITY: Belongs to the SsgA family. {ECO:0000305}.
