[https://www.uniprot.org/uniprot/CDUB1_CHLT2 CDUB1_CHLT2] Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. This protease possesses deubiquitinating and deneddylating activities (By similarity). Impairs ubiquitination and degradation of NF-kappa-B inhibitor alpha (NFKBIA), thereby preventing NF-kappa-B activation.<ref>PMID:18503636</ref>

Obligate intracellular Chlamydia trachomatis replicate in a membrane-bound vacuole called inclusion, which serves as a signaling interface with the host cell. Here, we show that the chlamydial deubiquitinating enzyme (Cdu) 1 localizes in the inclusion membrane and faces the cytosol with the active deubiquitinating enzyme domain. The structure of this domain revealed high similarity to mammalian deubiquitinases with a unique alpha-helix close to the substrate-binding pocket. We identified the apoptosis regulator Mcl-1 as a target that interacts with Cdu1 and is stabilized by deubiquitination at the chlamydial inclusion. A chlamydial transposon insertion mutant in the Cdu1-encoding gene exhibited increased Mcl-1 and inclusion ubiquitination and reduced Mcl-1 stabilization. Additionally, inactivation of Cdu1 led to increased sensitivity of C. trachomatis for IFNgamma and impaired infection in mice. Thus, the chlamydial inclusion serves as an enriched site for a deubiquitinating activity exerting a function in selective stabilization of host proteins and protection from host defense.
