Function
PIL1_ECOLI Propilin is the precursor of the pilus subunit, pilin, that forms conjugative pili, the filamentous surface appendages required for cell-to-cell contact during the earlier stages of bacterial conjugation, and that retract after contact is established. Mature pilin is assembled with the help of TraQ and TraX (PubMed:1464628, PubMed:6090426). Functions as a receptor for CdiA-CT from E.cloacae and E.coli, although it is not clear if this is physiologically relevant (PubMed:24889811).[1] [2] [3]
