Comments [?]

FUNCTIONSigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes.
SUBUNITInteracts with the RNA polymerase core enzyme.
SUBCELLULAR LOCATIONCytoplasm.
SIMILARITYBelongs to the sigma-70 factor family. RpoH subfamily.
