Function
DOTY_LEGPH Component of the Dot/Icm type IVB secretion system (T4BSS), which is used to inject bacterial effector proteins into eukaryotic host cells (PubMed:32513920). Part of a subcomplex which recruits effector proteins and delivers them to the core transmembrane subcomplex (PubMed:32513920). DotY and DotZ play a role in effector translocation, but are not essential and do not influence the stability of the subcomplex main components (PubMed:34816517). The DotY/DotZ main function is to optimize secretion by modulating the delivery trajectory of the IcmSW module and the localization of the machinery to the poles (PubMed:34816517).[1] [2]
