Subunit Structure
Component of an NADPH oxidase complex composed of a heterodimer formed by the membrane proteins CYBA and CYBB and the cytosolic subunits NCF1, NCF2 and NCF4. Interacts (via C-terminus) with NCF2 (via the C-terminal SH3 domain). Interacts with NCF4. Interacts with CYBB. Interacts (via the second SH3 domain) with CYBA. Interacts with NOXA1. Interacts with ADAM15. Interacts with TRAF4. Interacts with FASLG. Interacts with PARK7 (via C-terminus); the interaction is enhanced by LPS and modulates NCF1 phosphorylation and membrane translocation (By similarity). UniProt
Domain
The PX domain mediates interaction with phosphatidylinositol 3,4-bisphosphate and other anionic phospholipids. In the autoinhibited, unphosphorylated state an intramolecular interaction with the C-terminal SH3 domain precludes phospholipid binding and interaction with CYBA. Phosphorylation disrupts the autoinhibited state. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
