SPRY domain-containing SOCS box protein 1 - Q96BD6 (SPSB1_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Substrate recognition component of a SCF-like ECS (Elongin BC-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed:15601820, PubMed:21199876). Negatively regulates nitric oxide (NO) production and limits cellular toxicity in activated macrophages by mediating the ubiquitination and proteasomal degradation of NOS2 (PubMed:21199876). Acts as a bridge which links NOS2 with the ECS E3 ubiquitin ligase complex components ELOC and CUL5 (PubMed:21199876). UniProt

Subunit Structure
Component of the probable ECS(SPSB1) E3 ubiquitin-protein ligase complex which contains CUL5, RNF7/RBX2, Elongin BC complex and SPSB1 (PubMed:15601820). Interacts with CUL5, RNF7, ELOB and ELOC (PubMed:15601820). Directly interacts with MET tyrosine kinase domain in the presence and in the absence of HGF, however HGF treatment has a positive effect on this interaction (PubMed:15713673). When phosphorylated, interacts with RASA1 without affecting its stability (PubMed:15713673). Interacts (via B30.2/SPRY domain) with PAWR; this interaction is direct and occurs in association with the Elongin BC complex (PubMed:17189197, PubMed:20561531). Interacts with NOS2 (PubMed:21199876). Interacts with EPHB2 (PubMed:28931592). UniProt
The B30.2/SPRY domain is involved in MET and PAWR binding (PubMed:15713673, PubMed:20561531). UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
