Functional information

Function Uniprot A DNA-binding protein that acts in a fashion similar to H-NS protein upon overexpression, represses a number of genes including the cryptic blg operon, hns, papB and the proU locus. A subset of H-NS/StpA-regulated genes also require Hha for repression; Hha and Cnu (YdgT) increases the number of genes DNA bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex. Repression can be inhibited by dominant-negative mutants of StpA or H-NS.
Role Repressor
Protein family Histone_HNS
Structure (PDB ID) 2LRX
