    The protein

    [SW|Domains]

  • contains a [SW|RCK_C domain] at the C-terminus (according to UniProt, [http://www.uniprot.org/uniprot/?query=RCK+C-terminal+domain&sort=score x])
  • Effectors of protein activity

  • binds c-di-AMP, which likely activates export activity [pubmed|31061098]
  • [SW|Localization]

  • cell membrane (peripheral) (according to UniProt)
