pfam10075: CSN8_PSD8_EIF3K (This model is not part of the current CDD release)
CSN8/PSMD8/EIF3K family
This domain is conserved from plants to humans. It is a signature protein motif found in components of CSN (COP9 signalosome) where it functions as a structural scaffold for subunit-subunit interactions within the complex and is a key regulator of photomorphogenic development. It is found in Eukaryotic translation initiation factor 3 subunit K, a component of the eukaryotic translation initiation factor 3 (eIF-3) complex required for the initiation of protein synthesis. It is also found in 26S proteasome non-ATPase regulatory subunit 8 (PSMD8), a regulatory subunit of the 26S proteasome.
