Later during infection, both CT101 and CT228 regulate host cell exit via extrusion; CT101 (also known as MrcA) interacts with host inositol tri-phosphate (IP3) for calcium management (Nguyen et al., 2018) and, as previously mentioned, CT228 recruits myosin phosphatase (MYPT1) to the inclusion membrane (Lutter et al., 2013; Mirrashidi et al., 2015). This evidence concerns the gene BLTP2 and infection.
