Mol. Biol. 401:389-402(2010). CC -!- FUNCTION: Substrate recognition component of a SCF-like ECS CC (Elongin BC-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase CC complex which mediates the ubiquitination and subsequent CC proteasomal degradation of target proteins (PubMed:21199876, CC PubMed:15601820). Negatively regulates nitric oxide (NO) CC production and limits cellular toxicity in activated macrophages CC by mediating the ubiquitination and proteasomal degradation of CC NOS2 (PubMed:21199876). Acts as a bridge which links NOS2 with the CC ECS E3 ubiquitin ligase complex components ELOC and CUL5 CC (PubMed:21199876). Diminishes EphB2-dependent cell repulsive CC responses by mediating the ubiquitination and degradation of CC EphB2/CTF2 (PubMed:28931592). Regulates cellular clock function by CC mediating the ubiquitin/proteasome-dependent degradation of the CC circadian transcriptional repressor NR1D1 (PubMed:26392558). CC {ECO:0000269|PubMed:15601820, ECO:0000269|PubMed:21199876, CC ECO:0000269|PubMed:26392558, ECO:0000269|PubMed:28931592}. CC -!- PATHWAY: Protein modification; protein ubiquitination. CC -!- SUBUNIT: Component of the probable ECS(SPSB4) E3 ubiquitin-protein CC ligase complex which contains CUL5, RNF7/RBX2, Elongin BC complex CC and SPSB4 (PubMed:15601820). Interacts with CUL5; RNF7; ELOB and CC ELOC (PubMed:15601820). Interacts with MET (PubMed:15713673). CC Interacts (via B30.2/SPRY domain) with PAWR; this interaction CC occurs in association with the Elongin BC complex CC (PubMed:20561531). Interacts with NOS2 (PubMed:21199876). CC Interacts with EPHB2 (PubMed:28931592). CC {ECO:0000269|PubMed:15601820, ECO:0000269|PubMed:15713673, CC ECO:0000269|PubMed:20561531, ECO:0000269|PubMed:21199876, CC ECO:0000269|PubMed:28931592}. CC -!- INTERACTION: CC Q15369:ELOC; NbExp=2; IntAct=EBI-2323233, EBI-301231; CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}. Cytoplasm, cytosol CC {ECO:0000269|PubMed:21199876}. Note=Exhibits a diffuse cytosolic CC localization. {ECO:0000269|PubMed:21199876}. CC -!- DOMAIN: The SOCS box domain mediates the interaction with the CC Elongin BC complex, an adapter module in different E3 ubiquitin CC ligase complexes (By similarity). Essential for its ability to CC link NOS2 and the ECS E3 ubiquitin ligase complex components ELOC CC and CUL5 (PubMed:21199876). {ECO:0000250, CC ECO:0000269|PubMed:21199876}. CC -!- SIMILARITY: Belongs to the SPSB family. {ECO:0000305}.
