ospF

Gene
ospF
Protein
Phosphothreonine lyase OspF
Organism
Shigella boydii serotype 4 (strain Sb227)
Length
239 amino acids
Function
Catalyzes the removal of the phosphate group from the phosphothreonine in the mitogen-activated protein kinases p38, phosphothreonine in the mitogen-activated protein kinases such as MAPK2/ERK2, MAPK3/ERK1, MAPK8 and MAPK14 in an irreversible reaction, thus preventing the downstream phosphorylation of histone H3. This epigenetic modification results in inhibition of the transcription of a specific subset of proinflammatory genes, and ultimately to a reduced immune response against the invading pathogen. The diminished immune response enhances the bacterium's ability to disseminate and multiply within the host (By similarity).
Similarity
Belongs to the phosphothreonine lyase family.
