ADP-ribosylation factor 6 - P62330 (ARF6_HUMAN)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P62330: 14
 
Function
GTP-binding protein involved in protein trafficking that regulates endocytic recycling and cytoskeleton remodeling. Required for normal completion of mitotic cytokinesis. Plays a role in the reorganization of the actin cytoskeleton and the formation of stress fibers. May also modulate vesicle budding and uncoating within the Golgi apparatus. Involved in the regulation of dendritic spine development, contributing to the regulation of dendritic branching and filopodia extension. Functions as an allosteric activator of the cholera toxin catalytic subunit, an ADP-ribosyltransferase. UniProt

Subunit Structure
Interacts with ARHGAP21, ASAP2, ASAP3, HERC1, PIP5K1C and UACA. The interaction with ASAP3 is stabilized by calcium ions. Interacts with NCS1/FREQ at the plasma membrane. Interacts with RAB11FIP3 and RAB11FIP4. Interacts with USP6 (via Rab-GAP TBC domain). Interacts with ECM29. Interacts with TBC1D24. Interacts with MICALL1. Interacts with KIF23, forming heterodimers and heterotetramers. Interacts with GGA1 and RAB11FIP4. Interacts with SPAG9 homodimers, forming heterotetramers. Interacts with CYTH3. Interacts with EspG from enteropathogenic E.coli. Identified in a complex with RAB1A and EspG from enteropathogenic E.coli. Interacts with the V.cholerae enterotoxin subunit A1; this causes a conformation change so that the toxin can bind NAD and catalyze the ADP-ribosylation of Gs alpha. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
