Protein Daple - Q9P219 (DAPLE_HUMAN)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Required for activation of guanine nucleotide-binding proteins (G-proteins) during non-canonical Wnt signaling (PubMed:26126266). Binds to ligand-activated Wnt receptor FZD7, displacing DVL1 from the FZD7 receptor and leading to inhibition of canonical Wnt signaling (PubMed:26126266). Acts as a non-receptor guanine nucleotide exchange factor by also binding to guanine nucleotide-binding protein G(i) alpha (Gi-alpha) subunits, leading to their activation (PubMed:26126266). Binding to Gi-alpha subunits displaces the beta and gamma subunits from the heterotrimeric G-protein complex, triggering non-canonical Wnt responses such as activation of RAC1 and PI3K-AKT signaling (PubMed:26126266). Promotes apical constriction of cells via ARHGEF18 (PubMed:30948426). UniProt

Subunit Structure
Homooligomer (By similarity). Interacts with DVL1 (via PDZ domain); dissociates following initiation of non-canonical Wnt signaling (PubMed:26126266). Interacts (via C-terminus) with ligand-activated Wnt receptor FZD7; competes with DVL1 for binding to FZD7 and displaces DVL1 from ligand-activated FZD7 (PubMed:26126266). Interacts (via GBA motif) with guanine nucleotide-binding protein G(i) alpha subunits GNAI1, GNAI2 and GNAI3 (inactive GDP-bound form); interacts with higher affinity with GNAI1 and GNAI3 than with GNAI2 and interaction leads to G(i) alpha subunit activation (PubMed:26126266). Does not interact with GNAO1 (PubMed:26126266). UniProt
Domain

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
