CC -!- FUNCTION: Intercellular communication via tagB may mediate integration
CC of cellular differentiation with morphogenesis.
CC {ECO:0000269|PubMed:7744252}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255|PROSITE-ProRule:PRU00441};
CC Multi-pass membrane protein {ECO:0000255|PROSITE-ProRule:PRU00441}.
CC -!- DISRUPTION PHENOTYPE: Null mutations in either tagB or tagC lead to a
CC cell autonomous defect in prestalk differentiation and a 5-fold
CC reduction in the expression of the prestalk gene ecmA. Disruption of
CC regA in a tagB null or in a tagC null background results in higher
CC levels of sporulation. {ECO:0000269|PubMed:7744252}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the ABC transporter
CC superfamily. ABCB family. Multidrug resistance exporter (TC 3.A.1.201)
CC subfamily. {ECO:0000305}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the peptidase S8
CC family. {ECO:0000305}.
