Cytogenet. 153:77-80(2004). CC -!- FUNCTION: Component of the COP9 signalosome complex (CSN), a CC complex involved in various cellular and developmental processes. CC The CSN complex is an essential regulator of the ubiquitin (Ubl) CC conjugation pathway by mediating the deneddylation of the cullin CC subunits of SCF-type E3 ligase complexes, leading to decrease the CC Ubl ligase activity of SCF-type complexes such as SCF, CSA or CC DDB2. The complex is also involved in phosphorylation of p53/TP53, CC c-jun/JUN, IkappaBalpha/NFKBIA, ITPK1 and IRF8/ICSBP, possibly via CC its association with CK2 and PKD kinases. CSN-dependent CC phosphorylation of TP53 and JUN promotes and protects degradation CC by the Ubl system, respectively. CC -!- SUBUNIT: Component of the CSN complex, composed of COPS1/GPS1, CC COPS2, COPS3, COPS4, COPS5, COP6, COPS7 (COPS7A or COPS7B) and CC COPS8. In the complex, it probably interacts directly with COPS1, CC COPS4 and COPS8. Interacts with CK2 and PKD. Interacts with the CC translation initiation factor EIF3S6 and IKBKG. CC -!- INTERACTION: CC P10398:ARAF; NbExp=3; IntAct=EBI-350590, EBI-365961; CC Q9Y6K9:IKBKG; NbExp=1; IntAct=EBI-350590, EBI-81279; CC O14832:PHYH; NbExp=1; IntAct=EBI-350590, EBI-721853; CC P04049:RAF1; NbExp=2; IntAct=EBI-350590, EBI-365996; CC Q9P2S5:WDR8; NbExp=1; IntAct=EBI-350590, EBI-1054904; CC -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus. CC -!- TISSUE SPECIFICITY: Widely expressed. Expressed at high level in CC heart and skeletal muscle. CC -!- MISCELLANEOUS: Amplified and overexpressed in some osteosarcomas CC (OS), suggesting that it may participate in TP53 degradation in CC OS. CC -!- SIMILARITY: Belongs to the CSN3 family. CC -!- SIMILARITY: Contains 1 PCI domain.
