Dystonin - Q03001 (DYST_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q03001: 1
Cytoskeletal linker protein. Acts as an integrator of intermediate filaments, actin and microtubule cytoskeleton networks. Required for anchoring either intermediate filaments to the actin cytoskeleton in neural and muscle cells or keratin-containing intermediate filaments to hemidesmosomes in epithelial cells. The proteins may self-aggregate to form filaments or a two-dimensional mesh. Regulates the organization and stability of the microtubule network of sensory neurons to allow axonal transport. Mediates docking of the dynein/dynactin motor complex to vesicle cargos for retrograde axonal transport through its interaction with TMEM108 and DCTN1. UniProt

Subunit Structure
Homodimer. Isoform 1 interacts (via N-terminus) with PLEC (via N-terminus). Interacts with the neuronal intermediate filament protein, PRPH. Interacts with DES. Interacts with SYNE3 (By similarity). Isoform 1 and isoform 6 can homodimerize (via N-terminus). Isoform 1 interacts (via N-terminus) with ACTN2. Isoform 1 interacts (via N-terminus) with PLEC (via N-terminus). Isoform 3 interacts (via N-terminus) with COL17A1 (via cytoplasmic region). Isoform 3 interacts (via N-terminus) with ITGB4 isoform beta-4a (via cytoplasmic region). Isoform 3 interacts (via N-terminus) with ERBIN (via C-terminus). Isoform 3 associates (via C-terminal) with KRT5-KRT14 (via rod region) intermediate filaments of keratins. Interacts with MAPRE1; probably required for targeting to the growing microtubule plus ends. Interacts with TMIGD2. Isoform 9 interacts with TMEM108. UniProt
The microtubule tip localization signal (MtLS) motif; mediates interaction with MAPRE1 and targeting to the growing microtubule plus ends. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
