Component of the COP9 signalosome complex (CSN), a complex involved in various cellular and developmental processes such as photomorphogenesis and auxin and jasmonate responses. The CSN complex is an essential regulator of the ubiquitin (Ubl) conjugation pathway by mediating the deneddylation of the cullin subunits of SCF-type E3 ligase complexes, leading to decrease the Ubl ligase activity of SCF. It is involved in repression of photomorphogenesis in darkness by regulating the activity of COP1-containing Ubl ligase complexes. The complex is also required for degradation of IAA6 by regulating the activity of the Ubl ligase SCF-TIR complex. Arabidopsis thaliana (taxid: 3702)

In the complex, Cops8, which is the smallest subunit, probably interacts directly with Cops3, Cops4 and Cops7 (Cops7A or Cops7B). This signalosome is homologous to the lid subcomplex of the 26S proteasome and regulates the ubiquitin-proteasome pathway. It functions as a structural scaffold for subunit-subunit interactions within the complex and is a key regulator of photomorphogenic development [].; PDB: 1RZ4_A.
>PF03399 SAC3_GANP: SAC3/GANP/Nin1/mts3/eIF-3 p25 family; InterPro: IPR005062 This large family includes diverse proteins involved in large complexes [, , ]
The alignment contains one highly conserved negatively charged residue and one highly conserved positively charged residue that are probably important for the function of these proteins. The family includes the yeast nuclear export factor Sac3 [], and mammalian GANP/MCM3-associated proteins, which facilitate the nuclear localisation of MCM3, a protein that associates with chromatin in the G1 phase of the cell-cycle. The 26S protease (or 26S proteasome) is responsible for degrading ubiquitin conjugates. It consists of 19S regulatory complexes associated with the ends of 20S proteasomes. The 19S regulatory complex is composed of about 20 different polypeptides and confers ATP-dependence and substrate specificity to the 26S enzyme. The conserved region occurs at the C-terminal of the Nin1-like regulatory subunit [, , ]. This family includes several eukaryotic translation initiation factor 3 subunit 11 (eIF-3 p25) proteins. Eukaryotic initiation factor 3 (eIF3) is a multisubunit complex that is required for binding of mRNA to 40 S ribosomal subunits, stabilisation of ternary complex binding to 40 S subunits, and dissociation of 40 and 60 S subunits [].; PDB: 3T5V_D.
