Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q5T4F4: 1
Key regulator of RAB11-dependent vesicular trafficking during neurite extension through polarized membrane transport (PubMed:17082457). Promotes axonal elongation and contributes to the establishment of neuronal cell polarity (By similarity). Involved in nerve growth factor-induced neurite formation in VAPA-dependent manner (PubMed:19289470). Contributes to both the formation and stabilization of the tubular ER network (PubMed:24668814). Involved in ER morphogenesis by regulating the sheet-to-tubule balance and possibly the density of tubule interconnections (PubMed:23969831). Acts as an adapter protein and facilitates the interaction of KIF5A with VAPA, VAPB, SURF4, RAB11A, RAB11B and RTN3 and the ZFYVE27-KIF5A complex contributes to the transport of these proteins in neurons. Can induce formation of neurite-like membrane protrusions in non-neuronal cells in a KIF5A/B-dependent manner (PubMed:21976701). UniProt

Subunit Structure
Can form homooligomers (monomers, dimers and tetramers) (PubMed:23969831). Interacts with RAB11A (GDP-bound form); regulates RAB11A (PubMed:17082457). Interacts with FKBP8; may negatively regulate ZFYVE27 phosphorylation (PubMed:17082457, PubMed:18459960). Interacts with VAPA (via MSP domain); may regulate ZFYVE27 retention in the endoplasmic reticulum and its function in cell projections formation (PubMed:19289470, PubMed:21976701). Interacts with VAPB (via MSP domain) (PubMed:19289470, PubMed:21976701). Interacts with REEP1, REEP5 and ATL1 (PubMed:24668814, PubMed:23969831). Interacts with ATL2, ATL3 and SPAST (PubMed:23969831). Interacts with KIF5A and RTN3 (PubMed:21976701). Interacts with RAB11B (GDP-bound form), SURF4, KIF5B and KIF5C (By similarity). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
