Interactioni
Subunit structurei
Forms oligomeric structures: dodecameric arrangement of two trimer- of-dimer disks stabilized by the C-terminal tails, possibly through tail-to-tail interactions between the disks (PubMed:28325834).
Interacts with PTAC5; the formed complex associates with the plastid-encoded RNA polymerase (PEP) complex not only during transcription initiation, but also during elongation and termination, and with a stronger efficiency in illuminated chloroplasts. Binds to promoter regions of PEP-dependent genes (PubMed:23922206).
