CC -!- FUNCTION: Sigma factors are initiation factors that promote the
CC attachment of RNA polymerase to specific initiation sites and are then
CC released. This sigma factor is involved in regulation of expression of
CC heat shock genes. {ECO:0000255|HAMAP-Rule:MF_00961}.
CC -!- SUBUNIT: Interacts with the RNA polymerase core enzyme.
CC {ECO:0000255|HAMAP-Rule:MF_00961}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00961}.
CC -!- SIMILARITY: Belongs to the sigma-70 factor family. RpoH subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00961}.
