This domain is found in Low calcium response E from Chlamydia pneumoniae (CopN, also known as LcrE) and similar bacterial sequences. CopN is involved in the regulation of type III secretion systems (T3SSs). This protein contains three repetitions of a helical motif flanked by disordered N- and C-terminal extensions. This entry represents the third helical domain of this protein.	Domain
