The protein

Catalyzed reaction/ biological activity

• binds [protein|A208B4564A50D7BE2630DE40E8FAAF3C16236EE4|RapI] and inhibits its activity, this results in contiuned repression of the genes for the transfer of the mobile genetic element ICEBs1 by [protein|DD1C8F3A4809785BD6A6047D39B42AB2C605E161|ImmR] [Pubmed|17511812]

Protein family

• [SW|phr family] (according to UniProt)
