Chlamydia trachomatis IncA is localized to the inclusion membrane and is recognized by antisera from infected humans and primates.
Chlamydia psittaci produces a collection of proteins, termed IncA, IncB, and IncC, that are localized to the chlamydial inclusion membrane. In this report we demonstrate that IncA is also produced by Chlamydia trachomatis. C. trachomatis IncA is structurally similar to C. psittaci IncA and is also localized to the inclusion membrane. Immunoblot analysis demonstrated that sera from C. trachomati...
متن کاملTwo Coiled-Coil Domains of Chlamydia trachomatis IncA Affect Membrane Fusion Events during Infection
Chlamydia trachomatis replicates in a parasitophorous membrane-bound compartment called an inclusion. The inclusions corrupt host vesicle trafficking networks to avoid the degradative endolysosomal pathway but promote fusion with each other in order to sustain higher bacterial loads in a process known as homotypic fusion. The Chlamydia protein IncA (Inclusion protein A) appears to play central ...
متن کاملSTIM1 Is a Novel Component of ER-Chlamydia trachomatis Inclusion Membrane Contact Sites
Productive developmental cycle of the obligate intracellular bacterial pathogen Chlamydia trachomatis depends on the interaction of the replicative vacuole, named the inclusion, with cellular organelles. We have recently reported the formation of ER-Inclusion membrane contact sites (MCSs), where the endoplasmic reticulum (ER) is in apposition to the inclusion membrane. These platforms contain t...
متن کاملGolgi-dependent transport of cholesterol to the Chlamydia trachomatis inclusion.
Cholesterol, a lipid not normally found in prokaryotes, was identified in purified Chlamydia trachomatis elementary bodies and in the chlamydial parasitophorous vacuole (inclusion) membrane of infected HeLa cells. Chlamydiae obtained eukaryotic host cell cholesterol both from de novo synthesis or low-density lipoprotein. Acquisition of either de novo-synthesized cholesterol or low-density lipop...
متن کاملCharacterization of interactions between inclusion membrane proteins from Chlamydia trachomatis
Chlamydiae are obligate intracellular pathogens of eukaryotes. The bacteria grow in an intracellular vesicle called an inclusion, the membrane of which is heavily modified by chlamydial proteins called Incs (Inclusion membrane proteins). Incs represent 7-10% of the genomes of Chlamydia and, given their localization at the interface between the host and the pathogen, likely play a key role in th...
