| Protein Function | Component of the COP9 signalosome complex (CSN), a complex involved in various cellular and developmental processes |
|---|
| Biochemical Properties | The complex is composed of eight subunits, CSN1-CSN8. Six (CSN1-CSN4, CSN7 and CSN8) contain a PCI (Proteasome, COP9 signalosome and eukaryotic initiation factor 3, eIF3) domain, and two (CSN5 and CSN6) contain a MPN (Mpr1p-Pad1p-N-terminal) domain2. In Arabidopsis, the PCI domain-containing subunits are encoded by single copy genes, while the MPN domain-containing subunits are each encoded by two highly homologous genes. |
