FinP
FinP encodes an antisense non-coding RNA gene that is complementary to part of the TraJ [5' UTR]. The FinOP system regulates the transfer of Fertility [factor (bacteria)|F-like plasmids]. The traJ gene encodes a protein required for transcription from the major transfer promoter, pY. The FinO protein is essential for effective repression, acting by binding to FinP and protecting it from RNase E degradation.
