Mol. Biol. 401:389-402(2010). CC -!- FUNCTION: Substrate recognition component of a SCF-like ECS (Elongin CC BC-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complex which CC mediates the ubiquitination and subsequent proteasomal degradation of CC target proteins (PubMed:15601820, PubMed:21199876). Negatively CC regulates nitric oxide (NO) production and limits cellular toxicity in CC activated macrophages by mediating the ubiquitination and proteasomal CC degradation of NOS2 (PubMed:21199876). Acts as a bridge which links CC NOS2 with the ECS E3 ubiquitin ligase complex components ELOC and CUL5 CC (PubMed:21199876). Diminishes EphB2-dependent cell repulsive responses CC by mediating the ubiquitination and degradation of EphB2/CTF2 CC (PubMed:28931592). Regulates cellular clock function by mediating the CC ubiquitin/proteasome-dependent degradation of the circadian CC 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 and CC SPSB4 (PubMed:15601820). Interacts with CUL5; RNF7; ELOB and ELOC CC (PubMed:15601820). Interacts with MET (PubMed:15713673). Interacts (via CC B30.2/SPRY domain) with PAWR; this interaction occurs in association CC with the Elongin BC complex (PubMed:20561531). Interacts with NOS2 CC (PubMed:21199876). 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 Q96A44; Q15369: ELOC; NbExp=2; IntAct=EBI-2323233, EBI-301231; CC Q96A44; P40337-2: VHL; NbExp=3; IntAct=EBI-2323233, EBI-12157263; 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 Elongin CC BC complex, an adapter module in different E3 ubiquitin ligase CC complexes (By similarity). Essential for its ability to link NOS2 and CC the ECS E3 ubiquitin ligase complex components ELOC and CUL5 CC (PubMed:21199876). {ECO:0000250, ECO:0000269|PubMed:21199876}. CC -!- SIMILARITY: Belongs to the SPSB family. {ECO:0000305}.
