Adhesion G protein-coupled receptor B1 - O14514 (AGRB1_HUMAN)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Phosphatidylserine receptor which enhances the engulfment of apoptotic cells (PubMed:24509909). Also mediates the binding and engulfment of Gram-negative bacteria (PubMed:26838550). Stimulates production of reactive oxygen species by macrophages in response to Gram-negative bacteria, resulting in enhanced microbicidal macrophage activity (PubMed:26838550). In the gastric mucosa, required for recognition and engulfment of apoptotic gastric epithelial cells (PubMed:24509909). Promotes myoblast fusion (By similarity). Activates the Rho pathway in a G-protein-dependent manner (PubMed:23782696). Inhibits MDM2-mediated ubiquitination and degradation of DLG4/PSD95, promoting DLG4 stability and regulating synaptic plasticity (By similarity). Required for the formation of dendritic spines by ensuring the correct localization of PARD3 and TIAM1 (By similarity). Potent inhibitor of angiogenesis in brain and may play a significant role as a mediator of the p53/TP53 signal in suppression of glioblastoma (PubMed:11875720). UniProt

Subunit Structure
Interacts with ELMO1 and DOCK (By similarity). When bound to ELMO1 and DOCK1, acts as a module to promote apoptotic cell engulfment (By similarity). Interacts with MDM2; the interaction results in inhibition of MDM2-mediated ubiquitination and degradation of DLG4/PSD95 (By similarity). Interacts with PARD3 and TIAM1; the interaction is required for correct dendritic. localization of PARD3 and TIAM1 and for dendritic spine formation (PubMed:23595754). Interacts with MAGI1 (PubMed:9647739). Interacts with MAGI3 (PubMed:10748157). Interacts with BAIAP2 (PubMed:10343108). Interacts with PHYHIP (By similarity). Interacts with DLG4 (via PDZ domain) (PubMed:23782696). Vasculostatin-120: Interacts with CD36 (PubMed:19176395). Vasculostatin-120: Interacts with ARRB2 (PubMed:23782696). Interacts with BAIAP3; this interaction is direct (PubMed:9790924). UniProt
Domain
The TSP type-1 repeats in the extracellular domain mediate binding to phosphatidylserine. They are also required for bacterial recognition and binding to bacterial outer membrane lipopolysaccharide. 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.
