Anti-sigma-F factor Fin (IPR020115)

Short name: Fin

Overlapping homologous superfamilies


Family relationships



Fin (formerly known as YabK) is a small protein required for efficient switching from sigma(F)- to sigma(G)-directed gene expression during sporulation in Bacillus subtilis. Fin has been proposed to be an anti-sigma(F) factor which, by disabling sigma(F), promotes the switch to late developmental gene expression in the forespore [PMID: 21037003].
