RAB10 and infection: Infection with a ΔsidEs strain lacking all four SidE-family proteins (SidE, SdeA, SdeB, and SdeC) mostly eliminated the molecular mass shift of Rab10, while infection with a strain lacking the negative regulators of SidE-family proteins (DupA, DupB, SidJ, and SdjA; Black et al., 2019; Gan et al., 2019b; Qiu et al., 2017; Shin et al., 2020; Sulpizio et al., 2019) enhanced the intensity of the band (Figure 1a).
